A mechanic's simple stethoscope works wonders in situations like this. A screwdriver used as a stethoscope can be used as well, but is hard to keep steady on the moving spring barrels.

Did you wind it fully and play it before you changed the grease to eliminate the thumping? If so how long did it play? A good four spring motor should run about 20 minutes. If it didn't, it's possible that the springs have lost some temper and are weak. The only other possibility is a bad record or needle but I'm sure you thought of that.?
