My 1999 E300 Turbodiesel now has 322k miles. I have done the complete front suspension rebuild twice. The first time I bought the Lemfoerder bushing kits for the lower control arms and had a shop press out the old bushings and press in the new ones. The second time I bought new lower control arms with the bushings pre-installed. Total cost was similar in both methods and much more time efficient to buy the control arms with bushings.
If I knew the car would keep going like it has, I would have bought the special tool to remove and install the bushings the first time I did this job back in 2007 or so.
