1992 300E 4matic, should the trailing bushings on control arm look the same as the front ones? Mine appear to be partly gone but have no other indication that they are bad such as klunking or shimmy during hard braking. No wobbling during hard cornering. Can not get a good picture from CD manual. Another confusing thing is I went to autohous site to see what it showed and it said 2 per car and by my count it should be 4 per car. I didn't get any maintenance records with car so suppose someone could have changed the forward bushings without changing the trailing ones. Has anyone else run into this situation? and shine some light on it for me?

Thanks
Michael
