BMW 540i Problem Report
BMW 540i Alignment/Tire Wear Issue Due to Worn Rear Lower Ball Joints
The rear lower ball joints may wear causing alignment and tire wear issues as a result of the excessive play in these joints. Our technicians tell us a 4wheel alignment should be performed after ball joint replacement.
Did upper control arms in rear. Probably do lower if I keep the car. Had the shakes in front at 50 mph and braking the lower control arms took care of that. - 98540I
