If out drive cups never wore out, or were changeable with out taking the diff apart I would have jbwelded it last night.

I have thought about silly putty, but it gets very malleable when warm and I live in south FL. I do not know if it would hold.

I lack the disposable income to make the diffs "throw away" by jb'ing them.

I am going to try wadding it full of saran wrap tonight and binding the gears that way.
