Pretty new to the benz, and the rwd format in general. First a little background on the car, the car has 240,000 on it now, maintenance has been limited to oil changes before i got the car, im pretty sure that shocks, all suspension components, and everything else is all origional. So at freeway speeds mostly, and some lower speeds in the right circumstances, i get the wobble, pulling, etc. Now after a little research on this sight, i've learned that the biggest cause of this is the rear flex bushing on the control arm? I want to replace everything, im just not sure exactly what to replace. One guy says to replace that bushing, and upper and lower ball joints. But my question is what all should i replace at this mileage? i plan on shocks, i want to do tie rods because i feel they are worn, ball joints, i need to to the front right wheel bearing again as well. is there a write up somewhere with part numbers, or can anyone give me a list of part numbers, or at the very least, everything that needs to be replace at this point? Also for the flex bushings, i have access to a full shop, and from what i've read the biggest reason people use the poly bushings is because they are easier to install? but if i have a press, is it okay to use oem style bushings? im trying to do all this for as cheap as i can and there is a big jump between the poly bushings and oem rubber ones. Any help would be much appreciated.
