Thread: D3 Compressor and tyre life.

Welcome DD.

Personally I wouldn't be worried about the compressor. Even if it fails the car's still drivable, albeit slowly. My D3 was a Feb 07 build and in 4.5 years and 100,000km I never had problems with the compressor.

I would recommend you get some better tyres. No way I'd be heading outback on the Wranglers. As for tyre life, it is important to get a wheel alignment and rotate done every service or the D3 will chew through the tyres.

Again, when I sold the D3 with 99,800 kms the roadworthy guy knocked me back on the tyres due to age cracks. I thought they were good for another 10k but my opinion counted for zero. So that was two sets of tyres (first set GY Wranglers, second set Pirelli Scorpion ATR) in 100k. So maybe two sets in 88 is not so bad.

Whilst the compressors can fail suddenly with a fault such as a broken conrod, most seem to wear-out and therefore fail slowly. Sometimes its only the air dryer that gets too clogged which if replaced or rejuvinated early enough can prevent a failure of the compressor itself. The compressor can be replaced on the road-side as long as suitable tools are available and the vehicle can be jacked sufficiently and safely.

Poor wheel alignment greatly accelerates tyre wear on these vehicles, even when within LR specs as the tolerances are too generous. Worn suspension bushes as the kms accumulate is also a cause.

Thanks for the replies, the compressor was worrying me if it was a common problem and left me stranded with a van half way across the Great central Hyw or the like
Interesting the second set of tyres that went on the main contender was a set of Pirelli ATR's maybe the Goodyears were cheaper to put back on as it was on the market.
Yes I have been warned to keep the wheel alignment up.

Edit. I will always be carrying an other compressor (arb) better do some research on here to see how in an emergency I could inflate the suspension long enough to get home or back to a workshop ! Be OK if a bag doesn't slip then I guess not much you can do, or is there ?

Unless things have changed the Goodyears would be another $100 or so each.

I'm a mechanical dunce but I don't think an external compressor will help you. If you're that stressed about it carry a spare but you can drive the car with compressor.

Its worthwhile to identify the suspension ecu main power supply fuse so that it can be removed with the vehicle up if the suspension system develops a habit of dropping due to a fault somewhere.

White D3,

Whilst I am similarly endowed with your mechanical IQ, I thought I read somewhere here about one owner fitting something to their vehicle compressor that would allow inflation from an external source.

Not sure it was completed or able to be done but theoretically if your external compressor could generate the right amounts of pressure and flow etc then fitting another connection for emergency should be possible.

But as noted I am note sure compressor failure would be at the top of my list of potential issues for remote travel.

Gordon has such a kit under development:

A question that has to follow that comment is obviously - what would be your main concern ??

And thanks Rich for that link much more confidant now that takes the compressor off the worry list, just carry or install the kit. now to find out what might worry George.

Steep learning curve with these vehicles but probably not much more than most modern stuff, all lovely while it is working, but how often does it stop ? and what are the consequences if outside pick up range ?
