Mein Auto: '02 330ci
Question on rear suspension

My '02 330ci is 11 years old with 141k miles. I've already done RTABs but am now turning my attention to the rear suspension ball joints.

Realoem shows my car having an upper ball joint and a lower "rubber mounting". When I load in a same year M3, it shows the same upper ball joint as my 330ci in both positions. I'd rather put in upper and lower ball joints as in the M3 because they're probably stiffer and longer lived than the rubber mounting.

Will an M3 lower ball joint fit in place of the lower rubber bushing in my 330ci? Hoping somebody as already done this, if not it'll be to give a first try. Searching didn't turn up much.

TIA!

Since realoem shows different part #s for the trailing arm, I would think the lower ball joint would not fit.

They rarely wear out...what makes you think you need them?...more than likely you need rear dif bushing much more than Trailing Arm ball joints or lower rubber mount.

Thanks for the replys guys. I got the idea from turner motorsports which claims the ball joint will fit both upper and lower locations, as in an M3. They also recommend replacement after 100k miles; I'm at 141k. Just seemed like a nice upgrade. Will take the advice on the diff bushings and do them both.

On to the DIY section....

Once again, thanks to all!
