my pass side axel doesnt stay in the diff. it stays in but can slide back and for about a quarter in. enough to have the trn oil drip out.. i used 92 teg. axel .. do i need 94 cause they a little bigger or my locking ring?

 

it's the locking ring. Check to make sure it is still there and if it is and it still does replace the ring.

 

its still there just seems when i took it out to check it ,, it was loose around the axel.. no my trans makes whisling noise at low rpms i hope i didnt **** anything up with loosing oil..

 

Expand the snap ring a little and push that bastard in there.
