Well for me it was visual. The motor mounts should look solid, no cracks, and they should not be sitting lower into there mounts than the metal hoop over them. Youll see what I mean.
The tranny mount, is usally cracked or chewed up. Also you can grab the tranny or tcase and see if you can move back and forth. (this is obviously not a good way to do it because of the weight of what your trying to move) but it worked for me.
While you are looking at it, check your drive shaft again for any play at all. Check your ujoints again even though you replaced them.
Congenital Heart Disease is a reality for me, BOTH of my children have it. Please read up and become aware for future generations
