Joshdub: If you're talking about the control arm in the rear of the vehicle, I replaced mine. I cut out the stock ones and replaced them with polyurethane ones.

THIS!

Can you share where you got the bushing for the Rear Lower control arm?

Here is the backstory on this thread.......................................

I noticed EXTREME wear on the very very inside of the rear tires
I went to have an alignment
I wanted to reduce the negative camber to 1 degree or less
Alignment shop said couldnt set up alignment due to upper control bushing being shot
Took X5 to get UPPER bushing replaced
My wrench told me it was NOT the upper control arm bushing, it was LOWER bushing
BMW recommends the ENTIRE lower control arm be replaced NOT just the bushing
The entire swing arm unit is 500.00
I don't want to have a total bill of 2K for a 40-50.00 bushing

Sssooooooooooooooooo I am looking for the brain-trust input!

I am 100% CONFIDENT someone one here has found a way to replace JUST the broken part which is the BUSHING, and not replace the entire Lower Control Arm housing that includes the 50.00 bushing.......

There you have it.......

Insight?
