Mercedes-Benz E550 Problems

Tire Wear Caused By Worn Front Thrust Link Bushings on Mercedes-Benz E550

Problem Description and Possible Solution

Irregular and premature tire wear can be caused by the front thrust link bushings cracking and causing excessive movement in the suspension. The thrust link bushings are fluid-filled (to help reduce vibration), so if they crack, they will leak oil.

Still looking for the right fix. Dealer diagnosed Thrust arm bushing cracked but I didn't want to believe him at that time . My front tires have signs of cupping on the inside so something is wrong. A AAA mechanic could not see anything wrong with the bushing. I have noticed the slight and occasional popping sound when making a full right or left, typically in a parking lot. none of the linkages or any other components show visible signs of looseness or play. One additional noticeable sign is a slight grumble sound that peaks at 18 mph and vanishes below 15 and above 25 mph. As a result I thought it was bad bearings and I changed wheel bearings, the popping sound stopped for about 2000 miles and then returned slightly less frequent, but it's still there occasionally. I think I will change thrust bushing next or even the entire lower thrust arm with both bushings.
