Great, but what is an AWA? I potentially have this tyre wear issue, and my dealer wanted to charge me to check the alignment, because my car had done too many miles for warranty on this. I will approach the subject with them again if Land Rover now admit a issue. I reported the issue to them at 23000 miles, so the fact that it is now heading for 40k should not matter.

My Synchrones are now showing a little more wear on the insides than I would expect.

AWA = All Wheel Alignment

It involves the checking and adjustment of the toe, camber and castor (setback on the rear axle) of all four wheels (all four are adjustable). Once that is done, then the ride height has to be checked and recalibrated, then the AWA rechecked, altered, and so on until it is all perfect.

When mine was done, the front right and rear left tyre were showing inner edge wear at only 5,000 miles. The factory set camber was out of target data range on all four wheels; toe was out of range on both front wheels and one rear wheel; castor was pretty much ok; setback was out of range on the rears.

Since having this sorted, the car has driven better, MPG has improved and there is no noticeably unusual areas of tyre wear. My tyres did not need changing, but the wheels were rebalanced and swapped around anyway.

This is not a procedure that your local tyre shop can deal with, even if they claim to have the four-wheel alignment equipment - because they won't have the suspension ride height calibration kit, which is an integral part of the AWA process.

Winger, I got the impression of LR that AWA was more like a return reference than what you say. I am not disputing it but the woman I initially spoke to was not aware of the problem with tyre wear and told me to take it to my dealer and ask them to generate an AWA. Not sure if that helps, I would assume that all dealers will use a similar warranty process.

Sounds like a multi-faceted acronym. Interested in the alternative version - sounds like the W stands for Warranty then.

2006 Discovery 3 TDV6 SE Auto Arctic FrostDiscovery 3

Being one of the unfortunates with the "Clonk" at the base of the steering column appearing at about 2,500 km, can anyone advise whether the fix for this will affect the alignment as well ?

Thanks

It shouldn't, though you could of course ask the dealer to undertake a wheel alignment too!

2nd LR3 ( 05 SE7 and O6 HSE7) V8. Uneven Tire wear on Both. This time at 6k dealer is replacing at 100%. Mutiple unlignments on 05 did not fix problem.

I assume the problem is not with the tires since this happens on at least 4 differnt brands.

If it is indeed an alignment problem, why? Are they not doing a very good job ag the factory. Does it come out spec too easly. OR is this an inate problem with this vehicle.

I have been told it's cheeper to replace tires until the warrenty runs out than to fix problem.

Don't you have the dealer that says the camber cannot be adjusted?

That's my wonderful dealer.(I try to forget). My LR3 is in the shop right now. They are replacing tires. But the service manger did fill out and EPQR and I did not have to ask.

They are loopy!

Would you like me to send you the alignment data for mine?

Plenty of dealers don't have the kit to actually do the alignment properly; it is pretty involved.

However, for them to tell you that the camber cannot be adjusted is plain nonsense. Apart from the tyre (sorry, tire) wear, misaligned wheels detract from the driving experience, increase fuel consumption, potentially make the car less safe and just endlessly replacing tires is utter madness.

I am having my car delivered -now delayed till 10th March Sad - with its winter tyres mounted. Having read this thread, I thought that this might require such an All Wheel Alignment. The dealer claims that, since these tyres are the same size as the summer tyres, this won't be necessary. Is that correct? I don't want to ruin the tyres from day one!

More generally, the question is: is an AWA necessary every time you change between summer and winter tyres (assuming they are nominally the same size), each set being on their own wheels?

Thanks for any advice.

Eric

Provided that the alignment is correct, changing wheels/tyres won't make any difference. A slight difference rolling circumference shouldn't impact either.

The main thing to watch out for us uneven tyre wear; if that is presenting, then a wheel alignment would be in order.

Tyre shops will deal with toe, however the adjustability of the D3's suspension is beyond most, as they cannot deal effectively with camber and castor. A more specialist set of kit is required to sort that out.
