Rhino Pioneer Tray Noise

[rocket rod]

I have a full length Pioneer tray that makes a fair amount of wind noise, which is usually not a problem when going on trips but when travelling around town I could do without it.

Because of the noise I take my tray off and store it in the garage roof but fitting it again is a pain so leaving it on would be great if I can get rid of the noise.

Has anyone used one of these #43250 - Pioneer Wind Fairing - 1272mm / 50" | (https://www.rhinorack.com.au/en-au/products/roof/roof-trays/pioneer-tradie-accessories/pioneer-wind-fairing-1272mm-50-_43250) and are they worth it?

[LRD414]

Do you have the Backbone mounting system? I find the Pioneer platform is not very noisy, the only noise I hear is from the side rails. I read the Backbone is a major noise source.

I've got a backbone with a big platform. hardly any noise. Interestingly, I have a solar panel up there which is the full width of the platform. When mounted at the rear, there was lots of noise, but when I moved it to the front of the platform the wind noise went.

I have backbone and platform and it’s horrendously noisy compared to before.

[josh.huber]

I have the wind deflector but I havnt got round to fitting it due to my custom panel layout yet. Mine was noisy until I put my Tuffants with Cooper AT's on. Now the tyres are gone the rack doesnt bother me.

A major contributor is our roof design. It funnels the air down the back which forces it to increase in speed. Lrd414 has a half rack which starts at the back right above the hump in the roof. So less wind channelled. The back bone has holes for that channelled wind to get out of and so does the rack between slats. The one Scott has just mounted on slats has more from for the air to get out.

I too hate wind noise. My rack is noiser with my layout compared to rhinos, but I need it that way because of how I pack it. It's the same reason the previous poster says his rack is quieter with the panel at the front. The gaps in the rack without it allows the accelerating air to escape.

My next experiment is to put contact film off my little girls books onto the holes in the backbone system to see if it stops turbulence.

I have previously wrapped a 600t crawler Crane boom pendant system in 6mm Line to stop them flapping in the wind. The difference was incredible

With this being my previous experience I reckon the wind deflector will work wonders on our D4's

[kelvo]

I have the big (2128mm x 1426mm) Pioneer Platform with Backbone on my D4. I don’t notice any wind noise, I have more noise from the Maxxis AT980 tyres.

[rocket rod]

Scott
I have the full length rack with the 3 feet mounts along the roof, not a back bone system. I also have the 3 roof bars (I bought them before the platform) and if I mount the 3 bars with the front bar above the drivers seat, same problem, a lot of noise. So for me if there is anything above the driver's seat it makes noise, hence trying to find out the wind deflector's effectiveness.

[Victim]

I've also got the full length pioneer platform with the backbone mount. A workmate donated me some lengths of plastic uni-strut lid that clips neatly into the downward facing openings along the 5x cross beams. This definitely reduced rumble, but I've gotten used to the rest of the noise. I almost bought the deflector once I saw it, but held back due to lack of feedback. Watching with interest!

[p38arover]

I'd be interested to hear what you think of the deflector. Rhino stuff is so exxy that one doesn't want to spend the money unless one knows it works.

I have a full length platform on my L322 (thanks irondoc) and noise isn't an issue if I keep the sunroof closed. Like rocket rod, I have feet and three roof bars.

[DiscoJeffster]

I can’t fathom those who say the backbone and full length rack aren’t noisy? The difference was and still is incredible between fitted and not with the windows up. If there is a tailwind it’s bearable but holy crap when you have a good headwind, it’s awful. I’ve even got a full length spotlight that kind of acts as a wind deflector but that didn’t help.


I think the only variation to others is that I have two crossbars/tracks mounted to the top of mine that I mount my roof box to. Maybe that causes some additional turbulence??

[ATH]

I've got a full length Rhino with the backbone and get noise with cross winds but not much otherwise. I also got road noise from the Maxxis 980s when new but now they're about 3/4 worn that's quietened down.
I get more noise from the navigators side …..

Mine was horrendous at first. Then I put the tyres on. They were worse. Now I don't hear it at all.

I'll get the deflector fitted soon and report back

[shanegtr]

Full rhino platform and backbone my my D3. I hardly notice any extra noise from the roof rack. Even the wife agrees that she dosent notice any noise from it

[p38arover]

Even the wife agrees that she doesn't notice any noise from it

Can she hear it over her complaining about your driving and the fact that you own a Land Rover? [bigwhistle]

[SeanC]

Just crank the music up. Simples.

[Hawc]

I’ve got a three quarter length rhino platform. A bit of noise, but it doesn’t worry me. Noting the original comment about it being a PITA to put the rack on and off, I’ve got six of the rhino quick release feet, which makes this task pretty easy. Along similar lines, I’ve also got quick release brackets for the awning, which make it very easy and quick to take that on and off. I now happily change the roof configuration around easily, whereas before it used to be a RRPITA.

[p38arover]

To remove mine, I drive into the garage, lift the car to max height. Then I tie the rack to the beams above the car, unbolt it, and lower the car to drive out, leaving the rack suspended in the garage. It's a bit tricky lining up to refit it though.

I'll await your thoughts with the deflector installed to see if I'll get one.

[kelvo]

Here are two questions;

1 - The people with a noise issue did you cut the plastic cover strip as the Backbone instructions tell you?

2 - The people without a noise issue (From the roofrack) did you did you cut the plastic cover strip as the Backbone instructions tell you?

I don’t have a noise issue and did not cut the cover strip, it still runs the complete length of the roof. My D4 had no factory short or long bars fitted.

[DiscoJeffster]

Mine is noisy and cut.

Remember though, correlation is not causation.

I don't have backbone system and I have noise when I install a 3rd bar at the front on the lower part of the roof or put the platform on, hence the enquiry about the wind deflector.

[josh.huber]

Gee you put the pressure on me now. I'm a level 10 procrastinator! I've got to work out how to modify the brackets to fit aswell. I better pull my finger out. The noise isn't bothering me at the moment. The wife drives it to work

[DiscoMick]

Have you tried moving it back a bit? It reduced the wind noise on ours.
I have a theory that wind was bouncing off the windscreen and hitting the bottom of the front edge of the rack, increasing the noise. When I moved it back a few inches the wind noise reduced.
My racks are different, so it's only a theory and could be wrong, but it might be worth a try.

I could only move it back by about 5cm so I'm unsure it will make that much difference but I'll try that when I put it on in July holidays.

[irondoc]

I will modify my respnse - went for a rural drive the lasst couple of days and it was quite windy - there is lots of noise in a crosswind. However, 110km down the freeway withg no wind is not that noisy.

Watching with interest, I'm considering getting one of these platforms but not keen on a lot of wind noise.

Woohoo, im in group 2 too!

same, i drilled through the black strip and siliconed the front edge of same leading to the windscreen down. Also siliconed up the other mounting holes. Plus Ive riveted the long bars to each cross bar intersection. No noise.

Hi Josh,
Did you fit the wind fairing to the Rhino Rack Platform... how did it go?

I previously had a roof top tent installed on the D4 Rhino Rack Backbone (D4 Camping Setup with Rooftop Tent (https://www.aulro.com/afvb/l319-discovery-3-and-4-a/280284-d4-camping-setup-rooftop-tent.html)) and didn't really have too much of an issue with wind noise. But subsequently removed the roof top and relocated it on our camping trailer and installed a full length Pioneer Platform and the increased wind noise was quite noticeable. Some times more noticeable than others, so i suspect it depends on cross wind direction and wind speed as well. The shape of the D4 roof makes for interesting wind turbulence and pressure dynamics discussion no doubt. I am about to order the 1130mm Rhino Wind Fairing so interested in your feedback.

Cheers
Naps

[imaz]

I recently installed the rhino backbone, is noisy as hell. With or without the rubber strip cut.

I think it’s because of the not so aero dynamic roof structure when you have the tray.

I was hoping the length wise slats were supposed to be quieter than my previous front runner backbone width wide slat layout - but I was wrong.

[3Disco]

I’ve got a frontrunner 3/4 length rack. Seems Very quiet to me. Must be once you extend over the front dropdown portion of roof without a decent wind fairing or design that noise picks up.

[imaz]

Not sure if adding a light bar would help.

I reckon it will. It'll stop more air going into that funnel as the roof raises up.

Hey naps,

Fitting was a pain. I have heavily modified my platform to suit my specific need and lay out. The deflector can't be mounted on mine unless I work out how to build some brackets. I bought a light bar to go there instead. Which is still in the box.. To many other jobs on at the moment.
I'll sell you the wind deflector if your local. It's still in the box. Minor marks and has been assembled as I was going to fit it.

Thanks Josh for the feedback and offer... but being based in Melbourne metro poses quite a few limitations for the foreseeable future as you could imagine. Undertaking weekend projects on the D4 to fill the isolation void.... and in some ways getting the Disco 'all dressed up with nowhere to go!' My Pioneer platform setup is a little bit more straightforward I think, so I will order a wind fairing and post some feedback once fitted and had a chance for some test runs on the open road (whenever that might be!!).

Nup. Still awful. I have a 40” light bar sandwiched in and it’s still awfully noisy.

[DiscoMick]

Have you tried moving the rack back a bit to see if the noise reduces? It did on our Defender.
My amateur theory is a rush of wind is deflected off the windscreen and upwards. If it hits the front of the rack there is lots of noise. If the rack is further back the wind may go over the top of the front of the rack for less noise.
No idea if that's correct, but it's my theory.

If I recall you can’t. It’s designed to be fixed in position fore and aft on the mounting rails. There is only side to side adjustment available.

[OldGuy]

I to have the full length rack and it only seems to become noisy above 80Km/h. I read several reviews on the Rhino wind deflector and they were not very complementary, however I decided to make my own from a piece of plastic capping I had lying around, besides something to do while we cannot go anywhere, I also made my own brackets and used the top caps or whatever they are called to hold it on the front of the rack.

As you will see it is currently tied to the roof of the garage so have not tried it out yet. As it is not the easiest thing to attach to the car it will have to wait until I need to use it. It could be a while. [bigsad]

It is not the prettiest of things but hopefully it will be useful

.... I will order a wind fairing and post some feedback once fitted and had a chance for some test runs on the open road (whenever that might be!!).<br>

Well the package arrived from Rhino Rack mob and I spent a couple of hours fitting the new Wind Fairing. The process would have been pretty straight forward if the Rhino Rack parts were made to fit correctly.... I seem to have an ongoing problem with Rhino Rack Pioneer Platform gear... just minor annoying things. When the platform first arrived the bolts to attach the Rhino platform to the Rhino Backbone were incompatible... apparently they changed the bolt design between platform models. Dumb idea... so they had to send me a new set of bolts (which took a month to arrive). Now... I find that the wind fairing model supposedly compatible with my Pioneer platform has two of the mounting spacers that clearly do not fit and would never be able to fit without some serious modification! Good grief Rhino Rack you make some quality (but expensive) gear... yet manage to make some basic design gaffs... get your xxxx together!

Rhino rant over!!

The upshot of the installation exercise and road test: The wind fairing made a significant improvement in the wind noise... I recon it drops the noise by about 50%. You don't really notice much wind noise until you get to about 80kph, but previously it was very noticable by around 100 - 110kph. I am glad to say the difference with the fairing was a marked improvement driving at about 100kph on the ring road ... albeit on a pretty calm day.

Install:

165673
Of the 5 mounting blocks that slot into the Platform rails to secure the arms of the fairing underneath the platform... 3 fitted neatly into place, but the 2 outermost were about 2mm too long and not even close to lining up with the rails. I will be taking this up with Rhino Rack to see if this is again a case of a different set of fittings being required for the new model of platform.But for now... it was again a job for the Dremel.

165674 165675 165676
Emery wheel to shorten the plastic moulding and the plastic cutter to carve out a groove that would fit the platform rack. It all looked like a bought one once I had finished... but would expect that Rhino can make parts that fit together.

165677
The mounting system is pretty clever... and allows you to curve the fairing by offset positioning of the rack mounts, this enables the small feet of the plastic fairing to match the contours of the D4 roof. It all took the shape of the roof pretty well. Position and firm up the middle mount and then do the outer mounts to the appropriate curve... then firm them all up evenly.

165679
A neat enough result.... and for now it seems to work... time will tell. If not, the solution to noisy tyres, roof rack and snorkel air intake is the same thing... turn the music up!

I read several reviews on the Rhino wind deflector and they were not very complementary,

One would expect it to complement the rack quite nicely.

Or weren't the reviewers being complimentary? [bigwhistle]

[p38arover]

I have a full length platform on my L322 (thanks irondoc) and noise isn't an issue if I keep the sunroof closed.

After a week without the platform so that the Rangie could be detailed, and then putting it back on before a trip away, yes, it is noisy even with the sunroof closed. I'm now considering removing it altogether.

the reviews I read stated they were noisy and rattled, I must admit they were all US reviews. they do look good under the frame of the rack so I really don't know, I guess I was put off by the price and the uncertainty. I don't mind paying the dollars for a product that works but perhaps I was unfairly put off by the reviews.

Guess I will just have to refit my rack and report back. The deflector I made has about a 10mm gap to the roof line.

I just Goolged' Rhino Rack wind deflector reviews.

The Rhino Rack supplier responded quickly to my concerns about the misfit fairing. Pointing out that I had missed the small print that outlined that the fairing is not compatible with the new Pioneer Platform model. Apparently Rhino don’t as yet have fairings for the 5nnnnn models. My bad for not checking the detail.. Oh well...I just made one that is compatible :-)

That modification seems well worth it if you noticed a 50% drop in noise. I think it won’t be long before rhino makes the correct mounting for the series 5 platform you have.

I’m tempted to do the same as you and bite the bullet.

[BMKal]

Can't comment specifically on the Rhino Rack, but I have the Front Runner full length with cross rails, and it is very noisy without the small air deflector that comes with it. Admittedly, mine is probably a bit louder than normal because of the LED light bar between the front legs, but I have tried with and without the light bar, and with and without the air deflector fitted - and the deflector makes a significant reduction in wind noise - with or without the LED bar fitted.

I have been told that there is a version of this rack which has the rails running along the length of the rack rather then across it, and that this version is significantly quieter. Don't know how strong they'd be on a full length rack though without at least one cross member somewhere in the middle.

Gday Hawc- I have the same setup with the quick release feet. My awning is permanently mounted however and frankly I’d prefer another option. Doesn’t help when putting the platform on, with my son (I take the awning side as it’s prob about 15kg heavier and, as you’d know, a heavy and awkward overhead lift)

Any chance you could send some pics / part numbers for the awning quick release?

Hi Imaz,
I tried to apply some science to the process....doing a before and after run down the same section of ring road on the same day at the same speed to gauge the extent of noise reduction. ..and it certainly seemed to make a significant difference. Time will tell how it goes over different (rougher) road and wind conditions.

Just back from a 6 month road trip covering 24,000km...most of it on rough dirt tracks and off road. While the fairing does reduce the wind noise IMO, it seriously makes up for it through the incessant squeaking that all of the contact pads make once you get onto the dirt. The dust causes them to squeak and it drove us nuts...you could stiop it for a while by washing them down with water....but that gets lame pretty quickly, so I removed the fairing all together. Better off without and I plan to fill the space with a good light bar (suggestions welcome).

My noise got worse with a light bar! I have a Stedi.

[Macadamia]

thanks for the feedback. I was briefly looking at the wind deflectors so good to know I made the right choice.

I can deal with the noise when camping but I found it annoying to drive around town on and it tanked my fuel economy on the highway. For this reason I went with 6x pioneer quick release legs. They required a fair bit of effort to get them positioned to lock in with a tray, and are still a little fiddley getting it on and locked but no more than 10 minutes on and 5 minutes off. And I like that I can load up the roof rack for camping, and take it off to drive around the city.

They also ended up being cheaper than the regular legs + base kits

[shanegtr]

This talk of rack noise made me laugh recently. Had a mate of mine in my D3 recently who owns a Ranger with a roof rack (not a rhino rack) and he couldn't believe how quiet my D3 was with my rack. I'm sure there's just a little more sound deadening than a ranger to thank for that[thumbsupbig]

I know it's a big call but to get rid of the noise I had to take the rack off when not touring and that became a pain to do too. Best thing I've done to solve the problem long term and IMO I've got better rack.

First drive since fitting my rack but not a whisper from it up to 60kph, my old steel rack was noisy straight off the driveway.
I wasn't a fan of these racks when i first saw them but i do like the unobtrusive aspect when not loaded up and if i do need to remove i can do it easily myself.

Chasing resonance was just par for the course.

One thing that worked well, and may work in the roof rack - expanding foam - fill those cross tubes with it. It may well remove a harmonic!

Mine isn’t a harmonic, or whistle. It’s pure and simple turbulence noice.

It has been a while and have certainly used it on the car, couple of minor mods required to make it fit around the front of the rails but all good. The wind noise has virtually dissapeared, it does not rattle or vibrate. Early this year we did a trip up the Oodnadatta track then back down to Coober Peady, worked a treat might make another one that looks a bit more aesthetically pleasing..
