Gov lock reaplacing with.....?

Surprise surprise, the gov-lock in my rear end is a piece of garbage. It has been reliable though, in that it reliably gives me a one tire fire time after time. So I want to replace it with something else....

My question is can I just buy say an auburn lsd or Detroit locker, etc and replace the gov-lock with that? Is it as simple as that sounds? Or will I have to take out the ring and pinion, set lash, etc?

This is a GM 14 bolt 9.5" 3.73 rear end.

Eaton makes a very nice Posi for that rear end. It would be a much better differentuial. Don't get an Auburn.

Chances are that the gear on the governor is broke. That's the most comon failure of the Gov Lock.

Broken teeth on the governor and cam.

You can't just remove one differential and stick another one in. You must measure your bcaklash before you remove the old one and then set the backlash and bearing preload again when you install the new one.

Just about anything would be better than a Gov-Loc, but my pick would be the Eaton or the Tru-trac.
