So I have had this problem for a while. My 1990 240DL (wagon M47 trans) makes a pretty loud "clank" whenever I accelerate. So far I have replaced:
Trailing arm bushings
Torque rods and bushings
Transmission Mount (about 20,000-30,000 miles ago)
center support bearing and rubber mount
front swaybar endlinks
What should I check/replace next?
