You can do a visual inspection of the flex discs and motor mounts to see if they're worn out. cracks in the rubber mean tey're done, put it in park and grab the drive shaft and twist it back and forth while looking at flex discs to see if there's any play. try to turn the driveshaft carefully to see if the companion flange turns alot before the axles move. you may be able to feel the clearance between the pinion and ring gear. pry on the motor and trans w/ large prybar to see if the mounts are cracked (careful not to dent the pans). these items can clunk when worn out.
