I am considering changing all four rear control arms, on each side, of my 1987 260E W124. The price is $235 for the full set, but should I change these before or after I change the submount bushings? The car still wants to steer under heavy load after I changed the lower control arm bushings. I do not want to have to have the car aligned twice.

Thanks,
Bob
