Replaced with polyurethane bushings myself. About 2 hours and $99.00. The ride is <10% harder but better driving.

Made an audible clicking noise when the window was down while driving at 10-15 mph. Discovered by a tire change technician. Bushings were visibly cracked and deteriorated.

Felt a "thump" from time to time when braking. Occurred intermittently. Told by BMW service that tension strut bushing was problem. Cost $452.00 to repair as this is not covered by BMW's CPO warranty.

Need to replace front control arm bracket bushings after feeling shuddering in steering when braking at high speed.

started off with a small clunk at times, not all the time.
The guys that did the brakes noticed it.

When I am slowing down just around the same time that the transmission shifts from 2nd gear to 1st gear and vice versa the car will jerk.

Slight knock that comes from the front-end each time the brakes are applied or released. Additionally, the steering wheel gives a quick slight jolt or twitch. Repair is pending.

Have had this part replaced twice, at 20000 and 40000 miles. BAD design with the soft rubber insert. Was not found by the BMW dealer! Had to be found by alignment mechanic!!! Took him 5 minutes to find the issue. Car is driven around town and very little on the expressway.
front control arm bushings worn, had to replace both front bushings and perform alignment
