I had noticeable shimmy while driving. I replaced my steering rod ends and I still have a tiny bit of shimmy at 55 mph + , but it is much better. Just had new tires put on. It could be from a tire slightly out of balance or being out of align from changing the rod ends. We have no mercedes shops here so I brought my car in for the alignment today at the local alignment place. The Mechanic shows me by pressing with a crow bar from the side of the control arm at the bushing how there is sideways flex in the lower control arm bushings and In the lower ball joint he lifts it upward with the crow bar to show me how the ball will lift upwards. Is this normal flex they are showing me in both places? I noticed inside the lower control arm bushings there is rubber between the arm and the bushing thinking that rubber should flex there somewhat if being pryed with a crowbar. Does this rubber wear out or get soft? and should there be any release play on the lower joint like if you released the tension of it being pushed by the coil spring? I just don't like to be scammed or spend money replacing uneeded items. I would like a friendly opinion from my good friends here... Thanks!... Indi
