I got a flat on the freeway in my wifes 94 suburban half ton 2wd on the right rear. The spare is a little smaller than the tires on it now, and it took me a week to get it fixed. In the meantime the rear end starts making a clunking noise. So I pull the cover and everything looks fine.Changed the fluid and axle seals, and cleaned the magnet. I think they call this one a track lock. It has this little spring loaded leaver that locks the diff some how, but nothing looks broken, and nothing was laying in the housing, spider gears and ring & pinion all look fine. I got a new tire and it only makes the noise now when turning left, and side loading the right rear which is where the smaller tire was. Any ideas? I am going to drive it anyway. I am just nervous about my wife getting stuck or worse if the thing grenades. Anyone ever delt with one of these?

I don't know what to say other than to tell you they are called a gov-lock, as in governor controlled locker. Maybe that will help you turn up info on it.

the smaller tire was probably causing the "posi" to lock in. i bet its broken or worn out. those things are junk anyway. put some stress on it and it will shatter like glass. now would be a good time to upgrade to a Eaton.... or pull it and have a specialist tear it down and inspect it.

a simple solution is......

go to a bone yard get a whole assembly
they can be had for cheap they are so common!!!!!

for instance we can get a whole 8.8 (explorer) out of a yard with disc brakes for 75 bucks (or at least had gotten before)

I have alot of experiance rebuilding rear ends, I have just never delt with this particular one. Maybe the locking parts can be removed and it can just work like a regular open rear. Its not like we ever need it living in So. Cal.

i do not believe these have any friction material in them
just a centrifigal locking device that locks the spiders

ill look closer next time im in one

Squeezer you are correct. It works like an open rear until the lever flips out and catches. 10 sec message sent. Thanks everybody

The gov lock does use clutches and will clunk and chatter with the best of them. The 2 reasons they are called gov lock is #1 they engage when it senses wheel speed difference around 100 rpm. #2 they will not engage after 30 mph approx (the governor part). The lube worked for many I worked on in the early 80's at the local POS Chevy dealer that sold and ended up closed after I found a good profession.
