G80 Gov-Loc Replacement?

[Warthog]

I was working on my 1990 K2500 Suburban (sometime to be CUCV Clone) today and was checking the axles. Front looked fine but the rear has some spider gear teeth chipped and the maginet was caked in black goo.

Someone had been in it before and must have used a full tube of Orange RTV.

I didn't realize that it had a G80 Gov-Bomb. Not wanting to wait until it blows up.

I have never replaced a carrier or locker. But I have changed many axles shaft seals and bearings.

14bolt semi-floating
9.5"(??) 3.42 ring and pinion
mainly street driving, occassional off-road
stump pulling
stuck vehicle pulling
cheap (cash flow sucks right now)

Considering an open carrier or maybe an Eaton TrueTrac.

I don't wheel it and my wife says I drive like a grandpa

Looking for recommendations/tips

IMHO, if I didn't have the cash for a posi-trac/limited slip or a detroit (or even a lock-right lunchbox locker) I'd go with a plain jane open diff before I'd touch another Gov-Bomb. I still have bits and pieces of all the ones I've blown in the past in a pimento jar.

I have a Detroit Tru-trac in a 2006 Tundra V8 and it is really nice. When you stand on it, you get 2 tires pulling all the time and I never noticed it going around corners. Here are the pics from the install.

With the open diff, this truck wouild squeal one tire alot on start ups.

I found a 14 bolt FF on CL for $80. Had 4.10 gears. Prior to that I bought a 14B SF and 10B front both with 410s for $150. I know you will never get the 3.42 in the FF but you might be able to source a 3.73 front and rear on the cheap. I try to buy my 14B FFs open so adding a locking diff is cheap.
