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.Google+

Mercedes-Benz E350 Tire Wear Caused By Worn Front Thrust Link Bushings

Tires prematurely wear out at 10k miles due to axle sagging. MB dealership stated this is a known problem with the E350 2007 model through 2010 models. Weight of the engine causes axle to "sag" over time, not necessarily miles and "bolts" had to be installed to "strengthen" the axle.

Tires installed at MB dealership in December 2011. November 2012, tires have only 14,000 miles and the inner side of the tires are worn out. Had to have car alignment and 3 bolts installed in order for the front end to be aligned. Close to $300 for repair. Dealership stated this is a problem with the E350 models due to the weight of the engine on the axle. After a few years, the axle parts begin to spread causing the tires to eat from the inside.

Bushings are shot leading to tire wear.
I have just had all 4 of my tires wear on the very inside edge because of this problem. I have verified that this wasn't an alignment issue. This is unacceptable. My dealer is claiming they have never heard of it, but yet they have replacement bolts for the problem.

groaning in front when turning wheel or hitting bumps or starting and stopping. Have not taken in to dealer yet, but assume it is a bushing or suspension problem.

I have had this problem 3 times with my E350 2007 MB. The inside drivers tire know has large chunks missing and less than 7,000 miles on Michelin 30,000 tires. Bolts were installed on the front axle due to what the dealer stated was sagging due to weight of engine. Also stated this was a known problem with this model. Unacceptable!!!! should be a recall to repair. Not taking back to the dealer this time. Will try a local shop for repairs.

Experience "clunking" at low speeds and "bang" noise when turning tight corners. Both Lower Thrust Control Arms replaced (due to either bad bushing and or ball joint's attached)
