W208 rear end feels loose on shifts and acceleration
 

I've replaced all the bars, arms, shocks, 4 sub frame bushings. Only item that has not been replaced is the diff mount bushings, so it's logical that it would be this?

Prior to replacing the rear end would be loose on any bumps or imperfection on the road, that is now gone, just on shifts.

Has anyone replaced the diff mount on the w208 or w202? Any tips?

More rear toe-in.
