Rear Camber Adjustment?
 

I have searched, and found that the rear camber is somewhat adjustable, but where at? Is it the lower control are to hub bolt or elsewhere?

Thanks

I wouldn't mess with the camber front or rear. Take it to the alignment shop and let them know what you want/need them to do, like add a little camber so the inside of your tires don't ware out so fast. They will tell you what the pros and cons of that would be.
Just my 2 cents.

Looking underneath from the rear you will see the lower suspension arms. The camber adjustment is located at the inboard ends closest to the differential. To reduce camber, two spanners are required. Loosen forward nut and adjust camber by rotating rear bolthead until fat part of cam is toward the tyre. This is minimum amount of camber achievable (reduces wear on inner edge of tyre). Make sure the bolts are tightened adequately when finished. Some people worry about loss of cornering performance with reduced rear camber, I have not noticed any difference. I had an alignment done on my X5 after I adjusted the rear camber to its minimum, the resultant camber was still within worshop manual specifications.
Good Luck

Wow. This is amazing. I had no idea the rear camber could be adjusted. When you say, "To reduce camber", do you mean, reduce negative camber, correct? Negative camber is where the top of the wheel/tire tilts in towards the car. You are offering a procedure to lessen that tilt in, right?

I'd like to reduce is just slightly. You want some otherwise your X won't handle like a BMW. Most folks don't utilize all of the negative camber, as you'd have to be taking 50mph corners at 105 mph for it to mean the difference between staying glued to the road and oversteering. But these cars have so much understeer dialed into them, you'll never hit that point anyways. Cutting the negative camber in back to half of what it is would still leave you with a very glued to the road X.

Book figures for rear camber (all models are the same) are -1 degrees 50 minutes, +/- 20 minutes, with max' difference side to side of 30 minutes.
So, if your rear camber was -2 degrees 10 minutes (and wearing out your tyres), you can actually take it all of the way back to -1 degree 30 minutes, no problems. Biggest problem is, that you will not really know where the camber will end up if you do it yourself. The most precise way to change the camber is to have a wheel alignment done, and ask them to adjust the camber so that the rear wheels are more upright. You should be able to ask for an alignment printout and compare before and after adjustments.

Great expanation! Thanks! I may take some pics to post up after I'm done.

I had my mechanic reduce the camber to the minimum for increased tire life. It took about 5 minutes. The factory camber settings are for maximun cornering performance at the cost ot tire wear.

Do you recall what you wound up with for the minimum setting? -1, -1.5, etc..?

We did not measure as the mechanic did it by crawling under the car. I am getting about 25K life on my 19" Pirrelli's with relatively even wear at 32 psi all around

I have also neutralized the rear camber and my X handles fine! As a caveat I do have rear spacers so my rear track is 6 cm wider than stock. I think even if I did not have the spacers the X would still corner very well with the neutralized camber.

Rear camber adjustment kit?
 

Hey Guys, whats up? Im new here
I bought an 06 X5 4.4i in Feb 07 and already replaced the back tires once due to inner edge wearing thin. Does anyone know if they have a kit to fix the negative camber and maybe make it neutral? It would be awesome if the tire would sit squarly on the ground. My wife drives the X5 mostly and she drives like an old lady so it doesnt reallt matter. I want to fix this issue before I buy another pair of tires. I bought the lifetime wheel alignment at Firestone and can take the car in anytime for alignment jobs, but they said I was already at max minimum camber last time I took it in. What can I do?
Please advise,
Thanks,
Rick in LA

check the rear supsension checks out, also that tire pressure is correct....my x5 tires have worn out too on the inner edge and gonna go get them aligned to see if that fixes it, but the wheel can be seen clearly that they toe in at the top when you look at the car form behind, is yours the same

the rear is adjustable. if you're in LA make an appointment at stokes tire pro in santa monica. it's been a couple years but it was $90 for a 4 wheel alignment.

Anyone recommend a place for allignment in SF?
