L322 takes on Simpson Desert and Cape York

[irubix]

Alrighty brains trust. Need some help with planning a couple of trips, the simmo and cape york.

I'd like to get some feedback on vehicle prep and spares to bring + general advice from anyone that has done either trip (cape being the tele track).

My rig is as follows:
2005 M62 V8 L322 | 130,000 km

Completed by myself..:


Complete suspension overhaul in the front (Arnotts Air + Lemforder), Arnott shocks in the rear
Serviced trans + new cooler
New radiator + a main hoses
88deg thermostat
Engine had the heads off @ 100k (Timing chain guides done, all new gaskets etc) *previous owner*
Replaced valve cover gaskets (powder coated the covers red, brap brap) + new vanos solenoid gaskets - doesn't leak a drop!
New battery
Filter + Oil service every 7500km
ABS Module repaired
Discs and pads all round


Offroad bits..:

Light Truck 275/65/18 Falken Wildpeak AT x 5
Handheld GME 5w
OEM LR Roof Rack
Traxide Aux Kit w/ 60AH battery
Dometic 35L Fridge
Stedi LED high beams
All LED interior
2nd Air Compressor (Kings Dual)
IIDTool
Android Headunit w/ 4G and GPS etc



Thats a basic run down and I'm wanting to get some feedback on:

things to check (CV/Bearings maybe?)
any service items i should do
any advice or feedback on either trip in this particular vehicle
i gather i need a snorkel for the tele track?
winch setup that isn't $4k (and an eye sore)


I'm a bit of a lone wolf with this stuff at the moment, mid 30's IT professional, none of my direct friends have 4x4's or are really remotely interested in what I'm doing (all tried to convince me not to buy such a notoriouly unreliable vehicle.. haha) I'd be keen to meet up with some chaps/chapettes to convoy both of these otherwise I would imagine I'd be hitting these with one car/solo..

I have a lot of off road experience, far more time behind the wheel than weekend warriors, i used to work in remote mining exploration where 99% of my time was in a landcruiser of some description in the middle of nowhere. So that part I'm confident about (probably too confident!). My main thing is about being able to be self sufficient with repairs and knowing the terrain/expectations.

Thanks all! Keen to hear everyones suggestions.

You'll need one for Nolan's at least.

Dunno if I'd want to do either trip solo, although I'll probably be doing just that in the Simmo when I get my OKA, if I ever do.

Sat phone.

[irubix]

Sat phone.

Good point. Will probably rent one for the Simpson.

[Tins]

Good point. Will probably rent one for the Simpson.

Yeah. Probably wouldn't need one for the Cape, you aren't alone for that long up there. Dunno if it's any cheaper, but you can rent skins for your smartphone. I like that idea cos you are dealing with a familiar interface, which could be important in a crisis.

[Graeme]

The difficulty with the Simpson is trying to stay away from the crowds.

[irubix]

Yeah i hear the WAA line is less crowded which would be my preference, however, just as I'm saying that would be probably good to have a few cars passing per day in case something random explodes.

[Tins]

Especially with OS travel off the cards. Probably the CSR is busy as well.

[scarry]

We have done the Cape twice, desert crossings twice as well, all solo.

No issues, common sense, research,pack as light as possible, good set of LT tyres, and you will be OK.

Not just Nolans,Palm,and Logans can be deep, it often depends on recent rains.A snorkel is probably a must.

One year we didnt do Nolans as the water was 300mm over the bonnet of the D2.There is a way around it.

The other time, we did the OTT up and back.

Good luck, its a fantastic place.

Edit,i forgot to mention, probably going this year, for the first time, not solo, see how we go.[bighmmm]

The Cape,that is.

[irubix]

Yeesh, i dont think the old girl would survive that haha :), although i did hit a mud hole recently and ended up with water up the window, found out that water absolutely will get in via the top air vent into the HVAC system and into the cab... It does have a water vent out the side, but not made to handle alot of water or being submerged, thats for sure. Took everything to bits and cleared out the leaves and will probably cover the vent holes with some race tape + seal the blower motor entry area. On the list!!

[RSW Vogue 2004]

Have a look at the Zoleo instead of the SatNav. I bought mine from the "Captains Mate" in Qld, nice bloke and very helpful, also cheaper than anyone else.

[W&KO]

And the Rig Road should be even less crowded

LOL...that’s be Skippers Mate [emoji6]

Thanks for the heads up, I’ll do some research.

[RSW Vogue 2004]

close, no prize for me. hahahahahaha

[irubix]

So far need to do:


Snorkel
Seal up air HVAC air vent on bonnet + at firewall
Water bra


To take:


Spare belt and tensioner
Spare radiator hoses
2 x wheel bearings
Satphone/communicator


I also forgot to mention I've converted it to thermofans w/ fans from an old Jag + $5 PWM controller which is run to the cab. I have not yet got to the point of controlling the PWM/speed by temp sensor + have the thermofan's removed for this reason, i can't be bothered manually managing the PWM controller. She's all installed and tested though, works well. Also, probably need to make up a better shroud. Doing it again i would probably just buy bigger fans and make up a shroud from the get go instead of mucking around with the Jag ones, although they did come with the PWM fan control module which was a plus.

Whats the go with diff breathers? I know that they are extended, but I'm not sure where they exit.

[NUTTTR]

I believe the wheel bearings in these things are bit of a pain to swap...they are big and I believe require proper tools to pull and fit??

I believe you've done most of the cooling system already, so long as thermostat and water pump / trans cooler / radiator / expansion tank are done - have you done the head coolant cross over pipe behind the engine? It's a short hose with a plastic adapter. I'd also invest some time into making sure you've got pipes to bypass the heater controller on the strut tower. If one of those pipes go bad or the whole unit leaks, just bypass the lot. Hopefully you don't need a heater!

Diff breather for the front one goes over the passenger side coil covers on the engine into the V... Just.

The rear one I believe goes up to the fuel filler??

If your alternator is really old, that might be worth doing as preventative. Although, you could easily get it shipped to where you are if you are at a town and only need normal tools to swap it.

Lots of water on the Cape. Gets gets into your EAS compressor temperature sensors - can cause suspension failure. Did with us (D4s, but your setup wouldn't be too dissimilar).

Fit an emergency air up kit and test whether that spare Kings dual compressor your planning on taking has the grunt to lift the vehicle should you be caught out.

Hey, the air compressor is in the spare wheel well inside the car on the L322. They are a 'sealed unit'. I took some time to seal the whole boot area with sikaflex as i was getting some ingress due to a dodgy boot seal. Valid points around the suspension. I've seen a p38 with a custom valve block so each individual wheel can be inflated/deflated in the event of an issue with the suspension. Seems like quite the job to do for the L322 but it had crossed my mind.

Kings compressor is good for 125psi i think, which is a little off the 180ish(?) i think the L322 runs. I have a rebuild kit in the spares box for the compressor if for some reason the piston ring fails. I have heard of people plumbing in a second compressor to the main system and running in parallel to reduce the duty on the OEM one, food for thought, i did want to mount everything w/ a tank in the wheel well but need to figure out mounting etc. The kings compressor apparently draws 90AMP initially which is pretty high, if I was going to actually install I'd probably look for something smaller as the air tank would act as storage and a high LPM wouldnt really be AS required.

Thanks for your input! [smilebigeye]

If you have a rebuild kit... You are probably better off doing while it's still good, otherwise it could wear enough the new kit doesn't work.

There is also a guide somewhere where someone did hackery to trigger raising the suspension on the L322 manually by bridging connections on the EAS ecu... I don't remember where I saw it but it looked like a great solution looking for a problem!

[RSW Vogue 2004]

Try Rovacraft at Mascot for a Discreet Winch Mount, I have one on my 04 looks good as you will see.

Hey, thanks for that! Do you run a second battery at all to support the winch? Also, what was the cost of the winch plate?

Thanks :)

[RSW Vogue 2004]

Not sure of the price i think around $6-700, check with them.
Yes I do run a second battery in the boot drivers side.

Cheers

[irubix]

Anyone have any idea about the location of the transmission, transfer case and rear diff breathers? The front one exits in the engine bay I’ve found that one. For the cape I want to make sure they’re adequately high enough

[NUTTTR]

I'm pretty sure the rear one goes up with the fuel filler, you can trace it from under the car... I wasn't aware the transfer case had a breather...

Watch out if doing this, as I know the D3/4 and RR P38 EAS systems work on pulsing the valve blocks, and a constant voltage can damage them.

[irubix]

Yeah had a wee look and can kind of trace it to the arch. Its either extend or pop a filter on it in situ. I guess if im at the fuel filler height ill have other things to worry about

A one way valve maybe? You might get that corner deep in water and you don't want it flowing in then... Not the end of the world if you get 1 corner in deep

[irubix]

Would need to be able to vent both ways heating and cooling. Other option is to run everything it up the snorkel when I fit it. Recently saw a D4 get bogged up to the eyes in a mud pit and then start throwing gearbox faults. Assumed water ingress and it made me nervous haha

[irubix]

So a quick update have set the date for Cape York trip to two weeks in August. Have organised to go with a local 4x4 club..

Went to see a local fabrication guy today about a snorkel and he'll design a full stainless sealed unit to the airbox for around $750. This is built on the car as obviously, no jig. He's also modifying the OEM land rover roof rack to have mounting for 4 20l jerry cans, welded to the steel at the rear (i think this is the best place for it). Also doing up some protection for the transfer case as it is rather exposed currently. Will likely get him to do a full run of underbody and some sliders, but he's a young guy and doesn't have the equipment (yet) to bend 4mm plate.

Ordered a spare starter motor, an alternator rebuild kit (have the old unit from when it was replaced) and a GME XRS-370C4P pack.

Hopefully, this bull bar comes magically into existence before i leave to drive 4000km in North QLD roo territory.

So we moving forward!

Some late advice on spares to take remote. Have been told by somebody who works on L322's a lot, that you are more likely to need turbo hoses than a spare water pump.
(But take a water pump anyway.)
He suggests that L322 turbo hoses can develop leaks/split, and then turbo over-revs and comes to major grief.
So just make sure your turbo hoses are very good. Maybe source some silicone ones if in doubt.

Thanks kindly, i have the 4.4 M62 V8, but good advice for the general chat!

My trans threw in the towel last week, so check off tranny rebuild for a cool 6500... yessh.

[irubix]

Snorkel and underbody done and dusted. Snorkel is a bit bulbous and I'm told it was a serious f about to get it all in the guard.

Next on the list installing the GME radio!

That's a sweet snorkel! Where's your guy?
You have drain holes at the back of your bash plate?
Mine's just a plate with no sides, I'd be worried yours will get full of sand/assorted crap etc.
PS. I've just done the simpson; almost, turbo blew 5kms from big red.. 😔
The rangie just eats up the bumps on the dunes. It's brilliant at this terrain. Other cars with hard suspensions really suffer, but I had a smile on my face right up until I didn't.
Oh well, dropping in a new motor and will go back.

[irubix]

He's in Ipswitch, i cant imagine he'd want to do it again. Didnt seem too impressed, but i can give you his details if you PM me :)

He did the skid plates as well, they do have holes in them, but i agree sand and what not could get caught so ill keep an eye on them. Ill likely modify them over time to suit conditions.

Sucks about the Simo! You were coming W to E i take it?

Ive got some more piccies incoming, ive done some further mods in the spare wheel well, not 100% happy but it will get me to the cape and back and thats what matters.

Yes, W to E. Only 2 dunes to go before Big Red...
Think I may have split a turbo hose & spun it out. I had planned to change the turbo soon. Oh well, school fees...
I have some pics myself, might post a few. It's stunning out there.

[Strangerover]

Bit concerned about your choice of tyre. The towie who recovered my vehicle, which he had to drag over 3 dunes, specifically mentioned difficulties he'd had with an airsprung vehicle on oversized tyres that had sunk to the bumpstops. The tyres are too big for the wheel wells & won't turn, making a recovery very much more difficult and expensive as a flatbed might have to be used. Even your mates can't tow you on flat ground. This is why I've stuck to 265's when I got my muddies. Do you have an IIDTool? Essential. You'll need to run at off-road height at least, & the car won't let you do that if you're travelling over 50kmh. Wouldn't want it to drop to standard height coming up a dune, you won't get over it. The tool lets you set different height profiles.

Yeah I'm aware of the risk with those tyres and yep have an IID tool :)

If push comes to shove, i can remove the front quarters and inner liners which should give enough room.

Theres a guy in the states that sells a lift kit with strut/shock/air spring spacers to 2 inches which looks pretty good so if i continue on this path of making this a capable tourer, i'll probably look at doing that. The seller said he created them for his truck when he had a fault and bumpstopped his rig. He has a 4" lift but it required too much modification for my liking.

I also have UV curing fibre patches and some air lines + a compressor rebuild kit with me just in case :)

Can you remove the liners when the wheel wells are full of tyre? I had trouble when replacing my rear airsprings, and the wells were empty. The towie was REALLY pi$$ed off about the one he encountered where the wheels wouldn't turn, caused him no end of drama.

I worry about my airlines, they're coming up on 20 years old now. Pig of a job to replace the I should imagine, hard enough on the P38. That said I'd like to do it to further bulletproof the car. Any ideas to make it easier?

Re. Lift kits, I spend a fair amount of time on freeways at 110km/h &would be worried about stability if I couldn't get down to freeway height. I find that with the IIDTool I have plenty of clearance for desert & Vic high country, traction control takes care of any deficiencies if she lifts a leg. Still, if you're building a bush pig that'd be a great idea. More stress on CV joints of course, more to worry about..

[irubix]

Well, i just got back from Cape York. Did the Old Tele track.

Some notes:

1. 275/65/18 tyres rub on my Arnotts air springs when hitting (or getting close to) the bumpstops. So much so i blew a bag on the backroads travelling north (on the road). The car was in highway mode and was rubbing on the undulating roads. Will be moving back to 265 width when these tyres are done.

2. So much clearance on these rigs, you probably don't need underbody protection if you know how to take a proper line

3. Unifilter snorkel filters are incredibly useful, basically no dust through to the air filter, very impressed.

4. Dual seals on the doors don't help when you get stuck in a river haha

5. 91RON fuel economy is atrocious on the 4.4. Especially in low range. 39 l/100 on the OTT. Opal fuels are even worse.

6. The L322 acts like its twin locked, i have the version before they put the mode selector in, pop her in low range, point and shoot! It really is impressive.

7. Don't overcomplicate your 12v setup...

8. Make sure your drain bungs in the spare wheel well are correctly pulled in and secure, yes, you will flood your boot and air suspension compressor..

9. She laps up corrugations..

10. Not one issue that wasn't caused by myself thinking i know better than the Range Rover engineers (wide tyres, driving through chest height rivers without a tow etc)

Ill do you one better than that, i recorded the OTT in full (real time) on my go pro.

its mounted on the roof so you only see the bonnet but ill be uploading the full south and north sections to youtube.

Just had Graham’s LIAMS installed. Really nice controls for this type of trip, with a 3” selectable height range.

Just had Graham’s LIAMS installed. Really nice controls for this type of trip, with a 3” selectable height range.

One thing I've always wanted to know is if they control the crosslink valves as well? The offroad mode doesn't just control height.

From the system description & operation guide:

The following wheel travels are shown for on road and off-road vehicle operation. The difference between the two
operating conditions is a result of operation of the cross-link valve. When the cross-link valve is opened the
suspension travel is as given for off-road wheel travel. When the cross-link valve is closed the suspension travel given
for on road applies.

FRONT:

The off road mode wheel travel is:
l 175 mm bump
l 95 mm rebound
l This gives a total of 270 mm off road suspension travel.

The on road standard wheel travel is:
l 115 mm bump
l 155 mm rebound
l This gives a total of 270 mm on road suspension travel.

REAR:


The off road mode wheel travel is:
l 190 mm bump
l 140 mm rebound
l This gives a total of 330 mm off road suspension travel.

The on road standard height wheel travel is:
l 140 mm bump
l 190 mm rebound
l This gives a total of 330 mm on road suspension travel.

[rar110]

I’m sure Graham will give you an answer. As I understand the system it indirectly controls the height. The LR system seems to think its a normal height at all settings. I think Graham’s system essentially tricks the EAS into believing -25mm is normal, +25 is normal and +50mm is normal. The system adjusts the air pressure to EAS to ensure its at ‘normal’ height setting.

[Graeme]

The cross-link valves don't control height but perhaps on the pre-TR L322s the cross-link valves might be open whenever in off-road height mode.

LLAMS doesn't control any valves directly, only as stated above whereby the height sensor signals are altered to make the suspension ecu think that the vehicle is higher or lower than it is thus causing the suspension ecu to increase or decrease air-spring air volume until the height sensor signals are within the tolerance band of the target height.
