i bought my 420sel (1987) 7 years ago and dealt with the same thing....ended up with doing the entire front end for about 1200...after i purchased all parts...so all rubber underneath is new now

also went wheel bearings and rotors.....

did all the alignments and balancing...botom line is that with an older car you have to do the front end first and then go to the wheels....
