I have a MY00 with Koni Yellows/Ground Controls with Euro spec alignment, and a few months ago I notice a strange grinding/squeaking noise coming from the passenger rear. After doing some research, I deduced that the rear wheel bearing needed to be replaced. I removed the hub/knucle, and took it to my mechanic to have the bearings swapped. He informed me that the old bearing was so worn, that it fused itself into the knuckle. Yesterday, I picked up a knuckle/hub assembly from a local junkyard (car was wrecked from the rear but more toward the driver side). After installation of the new assembly, I noticed that there was no camber in the pass rear and there seemed to be some toe. So I figured, I'd ride around the block and see if the wheel just need to roll a bit to straighten out. First thing I noticed is that the car rolls straight, but only when my steering wheel is slightly turned to the left. The second thing I noticed is that the rear feels a bit twitchy when I hit bumps. The only thing I can figure out, is that the knuckle may possibly be bent. I also noticed that the ball joint on to toe arm, is almost touching the heat shield.

 

I had a bent pass rear knuckle, couldn't dial in any less than -4 degrees of camber when I lowered it. I measured from the brake disk to the knuckle arms on both sides to verify that it was bent (the knuckle arm that attaches to the toe arm). Unfortunately I replaced the lower arm and toe arm (as per Mr. Tire recommendations) before I realized the real problem. And yes when I replaced it with a good one, driving to the alignment shop was scary.....very twitchy. Hope that helped

 

It has been confirmed, the knuckle is bent

 

After a new knuckle, hub, and bearing installed and the car drives like a dream again! Thanks for the input guys.

 

Glad you got it sorted out. Sucks driving a badly aligned ap1

 

hey guys i am looking for a rear knuckle too.so my question is when you changed the knuckle and wheel bearings do you have to change the hub too or my existing one will be fine?do i need to change anything else?
thanks in advance,Andreas
