日産、ディーラーは、彼らが前にこの問題のことを聞いたことがないふりをしている!!

Mine has had maximum adjustment to remove the all negative camber at a recent wheel alignment and it's still measuring;

-1.22 deg on one side and
-1.20 deg on the other, both of are still far too much negative camber and totally unacceptable

Initial readings were
-1.39 deg
-1.4 deg on the other

No wonder it's been chewing up rear tyres EVERY 15,000KM!!

They've somehow managed to get the rear end back to -ve 1.15 deg camber,
but according to Nissan, this is "within spec!" Whatever the hell that means.

Re: T31 Wheel Alignment problem - Rear End

So the Rear Toe-in is definitely around 2mm?

Not saying any of what follows is your problem; just suggesting things that may help in case I mention something that gels.

Does your wife drive the car sedately or does she accelerate and brake hard like many women who just "Use" the car with disregard for its care? That will cause excess tyre wear especially if car is loaded with kids and stuff at the rear!

X-Trails are a bit soft sprung at the rear. The car could be low front and back due to Nudge/Bull bar, Towbar etc. and more bits and pieces than you realize. I notice you have added a some "Extras" that will definitely weigh the car down around 5 to 10mm.

Take everything out of car including Glove box stuff, mats, extra things in spare wheel well etc anything not in car when "As New" etc Park on level ground with all fluids at full mark (including petrol) and measure heights. That's the only way to tell if riding too low.

Get a Crash Repairer to measure the body to see if its distorted at all from abuse (overloading or rough roads).

Perhaps get the springs replaced with new ones from Nissan or perhaps you could get the rear ones reset at a spring/suspension place. If you don't intend going off road much DON'T get after market springs that raise the car or you may be quite disappointed with the harsher ride from raised springs.

You might however Need higher springs to compensate for the loads you are perhaps carrying, because excess weight at rear will cause your problem.

Did you buy the car new?

If not it could have been in anything you can imagine including being a hire car that's been hammered and thrashed in outback NT and sold interstate.

Its possible someone Lowered the car by fitting lowered springs.
This will definitely cause excess rear Camber.

If not its also possible that its been hammered on very rough roads and something is bent. The rear suspension on X-trails has been known to bend inwards if a heavy impact occurs at rear (big pot holes, spoon drains at speed, savage bottoming out etc).

Has the rear suspension links, axles and struts or the sub-frame etc been inspected for damage or misalignment or damaged body mount bushes.

Have the suspension bushes been inspected for damage or failure.

Your car should take normal loads/passengers no worries.

Interesting predicament and good luck!

What are these camber adjusters?

http://www.pedders.co.uk/files_nissan_x_trail



When raising, or for that matter lowering a vehicle, the camber angle of the wheel will change. I.e., the amount the top of the wheel leans in or out. Leaning in is negative camber, leaning out is positive.

2015/1/17(土) 午後 9:39 ogw*og*2

When raising the X-Trail T30, it is likely that the camber will become more positive and fall outside of Nissan’s specifications. As camber is not adjustable as standard on the X-Trail T30, we can supply a set of adjustable bolts that allow adjustments to be made once fitted to ensure the camber angle meets the specification. It is for this reason we always recommend that you have the suspension geometry checked after fitting our kit or making any other changes to the suspension.
