Diff Locks on '89 200TQ -Reply
You would not want to lock the diff above 15mph. It happened to me

controlled and will not allow the diff to lock above a certain speed (I'll
bet its 15mph). Maybe Superchips can .....
Doesn't the '89 have a Torsen center diff and the locking rear? How
does a Torsen handle in the braking case as compared with a locked
