I was doing a tour of inspection today (as you do) and came across this:

https://www.aulro.com/afvb/images/imported/2010/02/518.jpg

I've cleaned the area but you can see the scoring.

I tend to treat speed humps and traffic calming devices with mild contempt as you do when driving a Defender. There are many such obstacles where I live. So I imagine that when the rear end comes down the end of the bracket engraves a line where it and the ascending tail shaft meet.

I'm sure that doesn't add to the longevity of the drive train.

I guess that LRA will blame the man who installed the snorkel, the bullbar and driving lights and the Outback storage unit. :confused::mad:

So check it out.

mmmmmmmmm I wonder if this could be the cause of my what appears to be noisy exhaust...I will go and have a look now mahn thanks for the heads up

Well what do you know...I looked and thought nup, no where near, looks good...took a cloth to it just to make sure and sure enough there are score marks on the tail shaft not as bad as yours but they are there.

is that pin inside the rubber mount?
if so,, all should be OK,,

its probably noisey and bad engineering, but easily fixable.


But, of course, my glass is always half full---;):p

Bugger never checked mine, but even so its not a mark left from rubber its a score mark quite deep on mine left by something presumably metal (probably the pin)

Just checked mine and lot's of clearance. That said I can see that if the prop shaft was deflected up (as in when the rear is loaded down) this would be reduced - like when I was towing the trailer. But even so it is still a good way to the side of the prop shaft. Can't get a piccy at present as the car is dripping water everywhere from being washed and the P&S camera's battery is flat.

Don't you love hand built tolerances. To think I want to save up and buy a Morgan one day:)

Derek heaps of gap between ours also......did you take a cloth to the tail shaft and give it a wipe?

I looked at mine and though no way..but when I wiped it mahn was spot on the money

Yes its bad engineering and yes a pry bar and some leverage will fix it...

Pity about your glass though Pedro :p:D

On full suspension compression these bits will meet.

well its quite evident that they already have.....:)

and why mine is probably not as bad as yours as the defender has only been on one off road trip up at zig zag....early last year. since then its done the touring bit and commuting but not what I would call off road

As I said in the intro I negotiate some pretty significant speed humps "on road" in my local area but at no more than 50 km/h.

This is not an off road issue it's just bad engineering...moveable object meets immovable object during normal and predictable circumstances.

iv noticed this on all pumas, iv cheaked mine and all other fenders that come in and nothing, only on pumas?? iv then put mine on full cross up,, and its close but dosent touch, (td5)

Mahn I wasn't saying it was a soley off road issue only that us going to Zig zag and living in east hills with big speed bumps in the area could be the only reason for ours happening, as everything we drive now is flat and would cause no compression.......hence why I probably don't have as much noticeable catching as you do.

everything that has happened on the puma has been bad engineering has it not?

I can't disagree with what you guys have, I can only comment on mine and it would appear that without any horizontal movement in the prop shaft or the exhaust there is little chance of these meeting as there is a very reasonable gap.

Both of you have 07MY Puma's. I'll give Andy in town a call tomorrow and ask him to check his as well as it is an 07MY, mine's an 08MY, I'll PM Geoff and point him to this thread as his is an 09MY. I suspect this may be a hidden issue on either earlier Puma's or just luck of the draw as to who put the bracket on.

Yes I understand Lou.

If there is a sufficient body of evidence that this is an issue regardless of normal on and off road usage then we as owners should be letting LR know...before the tail shafts let go.

We as owners (customers) should be be Land Rover's most reliable source of feed back on its products.:D

I have plenty of speed bump around town and I too don't slow down much for them especially with the new shocks. I think the Land Cruiser behind me the other day nearly did some damage as he followed me over the first speed hump at the same speed:eek: By the second hump he'd slowed considerably!:twisted:

If it is happening it won't mater whether on road or off. So I think there is an issue with both your's and DB's.

Thanks for the photos Derek.

Mines an 09 MY albeit an 08 build. I think that the Morgan analogy is apt.:D

What gave it away that mine's dirty? Was it the finger print smears on the prop shaft:angel:

If I'm up to it (and remember) tomorrow afternoon I'll put a ruler against it and measure the gap and give the shaft a really good clean.

I suspect Morgan's are made with a lot more attention to detail some how.

So check it out.

Thanks Mahn ... I'm starting to feel like Chicken Little :eek:

Since mine's apparently fresh out of warranty I don't even wanna go and look, but I think on the 130 the exhaust is routed differently...

Just checked mine (2008) after a trip down south with a bit of extreem suspension travel and my vehicle also has the scratches.

Dont forget guys (and Girl) that the exhaust also moves horizontally.... Shaking and rattling along ;)

That gap, combined with a compressed suspension AND exhaust vibration will close up very quick...

Suggest forcing muffler across a bit too when checking clearance... :cool:

OK pic's of a properly cleaned prop shaft and the exhaust bracket on mine.

From below:

From above:
https://www.aulro.com/afvb/images/imported/2010/02/415.jpg

So it would appear that I don't have as significant problem as others but there a three small scratches on the prop shaft in line with the bracket. These show up nicely from the camera flash but I've inspected them and they are more of a mark in the paint than the surface.

I've looked at the other exhaust mounts and everything looks in place. There isn't a lot of movement in the exhaust line on mine. Mahn, Lou, can you check the other exhaust mounts and check that they don't look like the exhaust system has moved at all or any mounts look stressed. I suspect you will find they are all OK too.

The alignment on mine was so bad that the lugs would pull free from the rubber support and give the tail shaft a good old seeing too.;) I did put some pictures up in an earlier thread on this.

Cheers.

Justin,my son has been complaining for awhile about a strange noise occasionally coming from the Puma.Guess what,that exhaust bracket has been rubbing on the rear drive shaft,exactly as per the earlier posts.
Its actually worn a fair bit off the lump on the end of the bracket:eek:
I will try & get a photo & post it up.

Now a trip to the stealers to see if they can fix it successfully the first time.

That is, after it has been to MR for a service,so anything else that is found can be fixed in the one go.

What's the noise like as I have a knocking under mine when pulling away in first and it really really sounds like an exhaust knock to me but couldn't see anything obvious when underneath..

however i don't know what others are like, but I got a fair bit of movement on the exhaust system when giving it a rock.

scarry
17th May 2010, 07:09 PM
It is like a knock.The best way to tell if yours is doing it,you will see the telltale signs in the driveshaft exactly as the photo's in this thread.

Good luck

Arr,found the pic.

Recon you have two problems,drive shaft rubbing & something else:mad:

I will try & get a pic of sons driveshaft & post it up as it has rubbed worse than any of the pics here,but maybe it's done a bit more flexing.

since i have a td5 i will never have this prob:D:wasntme:,

but just take your exhaust off like i have and you have no probs:D:D:wasntme:

but yes,,, been serious,,, this is a prob on pumas and pretty much all of them do it,, but there has been no problems due to this happening

2007 Puma - 52,000km - but, new 2009 rear prop shaft at about 38,000km - no marks and heaps of clearance. I wonder if the revised prop shafts are different enough not to rub?

nope, it sat in a yard unsold for 9 months, but I did get it a lot cheaper.
Have yet to get the lanotech on to it.

Nope! Mine has touched slightly, I think only when loaded up and off road.

Is anyone aware of a Land Rover fix to the exhaust bracket - rear propshaft contact problem? My dealer attempted a mild 'bend' to the upper hanger to improve the clearance to the propshaft, however after only 100kms the rubber block was sliding off the upper hanger so I tapped the bend out and put the hanger back in alignment.

I'm not keen to let the 'ring-barking' continue until the propshaft fails. I imagine it is high tensile steel and would not take kindly to significant scoring or grooving.

Looking forward to some guidance.
