Your mileage may vary...
I have blown up two of the stock Gov-Bombs in my 1995 1/2 ton Suburban.
The first was the stock one and the second was a gamble unit I pulled from the junkyard as I was low on the money tree at the time.
After the second one went boom, I had the cash in hand and put a Detroit TrueTrac in the rear.
All was good and it worked flawlessly.
We did have an aluminum wheel work its way off while we were going down the road at 35mph.
The Sub wobbled and shook and then set down on the drum and we came to a stop.
It was here that I later suspected we bent the axle tube on the rearend.
Some time later while in a parking lot, I felt the rear do the ever painful load up and pop as I turned.
I limped it home a couple miles and then found a shop to do the work.
He found the axle to be bent slightly and fixed it back up to be totally straight.
Since these units are not supposed to ever break, you cannot get new parts for them when they do need them.
So into the recycle bin it went.
I now have a Yukon Duragrip in the rear and it works like a champ as well.
The Yukon does not lock the rear wheels at slow speeds like the Detroit did, so no more tire scrubbing at slow speed like I have a spool in the rear.
They both work great.
But the fact that if I have a failure on the Yukon, I can rebuild it was what sold me on using it over another Detroit.
This is what was in the bottom of the housing...
