BMW 323i Problem
Average Mileage: 130,125 mi (47,000 mi - 204,000 mi)

had to replace lower control arm bushings, but at 180,000 how can u complain.
I thought I needed new brakes and could swear I could hear a grinding noise coming from the brakes, however I also heard a "clunk" noise coming from under the car as I came to a stop. It was the "clunk" that concerned me because I once had a drive shaft that failed me in another older car I owned (Ford). Took the car into my mechanic and just one test drive around the block he knew what it was! Not the brakes, but the control arm bushings! He fixed it and it sounds great now.

I have had this problem ever since I bought the car used, my mechanic thinks that it is weak struts and he has inspected it twice. I tried to tell him that I read about the worn bushings, but he says they are fine. I guess I have to find a new mechanic...

It hasn't started clunking yet but it feels like the car is sliding forward as you break. I know it will start to deteriorate fast so I'm getting the upper control arm bushings checked and I'm pretty sure that's the problem
