| Check the sub frame bushings for any silicone leaks. If there are none I would leave them alone. However at least check the bolts for adaquate tightness. The problem only appearing when driven would appear to be related to oil viscosity so give the diffey fresh fluid. You need to change it anyway. Be sure to use only a single rating GL5 gear lube. Mobil1 synthetic 75w 90 is a good choice at about $10 per qt and you need almost 2 qts. There are other choices like Valvoline synthetic, Castrol synthetic, etc. just make sure of the single GL5 rating. Note the amount of black magnetic sludge on the drain plug as it will tell how much wear the diffey has experienced. IMPORTANT: pull the refill plug out first because if that is suck and you drain it a refill is darn near impossible. This also holds for the manual tranny service.
