I've got an 84 and an 81 and have had my fair share of clunks. First things first, tighten up all the bolts/nuts in the front end...3 13mm nuts on top of the strut towers, the two big crossmember bolts at the base of each strut tower, the rear control arm bracket bolts, the bushing bolts (not too tight), swaybar bolts (make sure the sway bar end link bushings are sitting right in the cup washers, if not, they could pop when the swaybar goes up and down). Second, check the wheel bearing tightness (this was the source of both my 240 clunks). Jack up the car and grasp the tire at the 12 an 6 o'clock positions and try wiggling the tire back and forth...if you feel looseness or hear a loose-bearing type noise, take the grease cap off the bearing, remove the cotter pin, tighten the castle nut 1 notch and put the cotter pin back in along with the grease cap. Let us know if any of these things fix it.
