I am experiencing technical difficulty with my lap top and cannot find the rear suspension diagram. If any one can link it, the parts I replaced were left and right ball joint (same part #), left wishbone and right wishbone (different part #s). I have the invoice with part #s at my office and will post those part #s tomorrow.

I researched lots of places and lots of manufactureres and decided to go with Rocky Mtn Euorpean, they had the best prices on the manufacturer I chose. I went with Lemfoerder (sp?) on both.

What I replaced on mine are #02 ball joint part #33326767748 (one per side) I paid $40.12 each from Rocky Mtn European (BMW Parts, Porsche Parts, Audi VW Mini Volvo Saab Mercedes Auto Parts - RM European Auto Parts)
and #11 left wishbone part #33326770859
and #11 right wishbone part #33326771860
I paid $100.57 each also from RM Euro. There are many choices but I chose the Lemfoerder for both. There are cheaper and of course more expensive replacements.

Here is a link of the parts diagram. Penske Parts - Technical Diagrams - E53 X5 3.0i (M54) SAV

Hope this helps.

You are weclome, this forum has helped me many times, it is awlays a pleasure to try to return the favor.

After all the new parts were installed, the allignment guy said he had a lot more adjustment to play with so he feels this should solve the inner tire wear problem. I went with the Lemfoerder parts because my Indy shop swears by them and I could buy them for what he pays for parts. Good luck.

When I discovered the inner tire wear I had an Indy allignment guy check the allignment, around $140, +/-. The same guy installed both left and right rear wishbones, and both rear ball joints and then added specified weight to car and re-alligned. He checked allignmet without weight and after specified weight. He had over 8 hours labor and charged me $375 which I thought was very fair.. Hope this helps.

How many was on the car when that happened?
I believe BMW tech told me that the rear ball-joint goes bad first, the upper control arm (or wishbone).
Thanks.

18" snow tires were installed on my X5 in October with 9/32 to 10/32 tread remaining (1/2 a winter of usage on a different vehicle). After 5,000 miles of use this winter I noticed uneven wear on the inside shoulders for both front and rear tires. The rears are much worse. First and 3rd photos are the inside edges.

Alignment was done at 66k miles (see PDF), 78k when snow tires were removed.
Comments?

I don't see a "camber bushing kit". Did BavAuto stop selling it?

====================
BMW does offer a Value Line kit (which includes bolts and nuts) for the rear arms: 33-32-2-180-423 SET OF CONTROL ARMS, REAR. List price = $484, wholesale $387.

This is still quite a bit higher than Lemforder:
