Camber off After Bearing Replacement

CJW2OO4 · 05-05-2013, 12:58 PM

I am stumped as to why the camber is off on my car after the rear bearing replacemnt. I was wondering if you could offer some advice as to what could be the culprit. The camber is off on the left side of the car. Its at 3 degrees while the right is at 2.6. (z4 non m have high camber from the factory.)

The only thing I did differently on the left hand side is remove the left side half axel shaft.

Bearing replacements often require banging with heavy devices and it doesn't take much to make a car out of alignment.

That's all I could think of.

If bolt 10 and nut 11 in this view of the rear suspension were loosened during the bearing replacement, your camber will likely be off: http://realoem.com/bmw/showparts.do?...39&hg=33&fg=30.

Adjust your rear camber by rotating this eccentric bolt and nut after loosening, then re-tighten when the camber is correct. Rear toe may then need to be adjusted by loosening 3 bolts marked as 19 on the above diagram and moving the trailing arm mount.

^ WHS.

Unless you marked the position of the eccentric bolt before you started it will be a matter of luck if you'd managed to refit in the same position afterwards.

Thanks for your assistance guys. I will be bringing the car to Bavarian Performance Group to have them take a look. TFT said they could do nothing for me.
