a) engine shocks
b) motor/tranny mounts
c) check valve adjustment
d) timing chain tension
e) injection timing check

Mine shook pretty bad and I found that the drivers side motor mount was trash. I have changed all mounts and the shock and it helped alot. Also performed the valve adj. and will be replacing the timing chain soon. This is all in the '85 300D.
