I have a 2003 bnw 325xi and when I turn my wheel I feel
and hear a grinding noise feel like it's a wheel berring or
ball joint I think. I need to know before it gets worse
Most probably time to replace the CV joint on one side. I would do both, the other is probably not far behind. Have a shop get it up on the lift to verify and replace.
