You likely have the standard suspension, but presence of the sport steering wheel and such isn't a reliable means to check. You need the build option list of your car to be sure.

Either you have this perhaps from the window sticker or sales contract or my asking your local dealer (most will do this for free when you provide that it's your car) OR go on line to BMW Baureihenarchiv · BMW Vehicle Identification Number Decoder · bmwarchiv.de to get the build list from BMW itself.

You definitely do NOT have sports package, I can tell by looking at your avatar.

Get the rear comfort air springs from Arnott.

Im brand new to this site and wanted to chime in on this topic. Tomorrow, i will be taking my 2006 BMW X5 4.4i, non sport, to get checked out. My rear inner tires are getting an ass beating and I believe its because of a camber issue. My question is: what will cause the camber to be too negative? what part has failed and needs replacing? Last, how much do you think this will cost? I know mechanics will throw in there pricing but realistically speaking, I will like to know what numbers come out of this before I step into the garage just so I know. By the way, thanks fo any help that may come from this. Ive read a few other posts on other threads and there are a lot of savvy people here.

You don't mention miles on your car, service history or rear suspension (air springs or metal springs).

Assuming you don't have leaking air springs or weak coils, that the air in the tires has been correct for the last few years, etc.

THE most likely would be the (replaceable) ball joint in the lower rear control arm and the upper control arm (the magnetic steel one). When you replace these, you also do the link as well. Look for a rear suspension video on Youtube from a show in the greater NY area. Similarly look for the rear ball joint replacement for an E39 (same parts: link and ball joint) done by Bentley (the guys who do the shop manual).

I replaced all of this on my 02' X5 with 230.000 km on the clock. Definitely an improvement. I would (do as I did) suggest you replace the rear shocks at the same time with Bilstein B6 versions (yellow).

f you have rear inner camber issues and t

That vin decode gives the day the car was made. I had 12/02 now I have 12/7/02!

If you have 80,000 miles or more on current suspension it is in the range to be rebuilt. Over 100,000--quite likely. That said, I would get the X off the ground and inspect all suspension pieces carefully before replacing anything. If the suspension checks out, get an alignment check. BMW alignment specs have negative camber for better handling and tires often wear on the inside even when the suspension is fine. Castor can also wear similar to negative camber--another reason to get your X aligned if the suspension checks out OK.

Are you replacing the rear airbags because there is a problem with the air system or is it intended to reduce the wear on the inside of the rear tires?
