I have a 1994 BMW 525i with 146k. At 50 mph the left front tire is vibrating. The vibration stops around corners. I have the wheels balanced 4 times and changed once. Problem still exist. I'm not sure how long I want to keep the car, so I don't want to sink money into this repair. My mechanic told me after consulting with a Porsche race shop the lower control arms were causing the problem, specifically the bushings. About $400 to replace. My questions: 1. could this cause the problem, 2. can I do this repair myself, 3. can I just replace the bushings.
