I almost bought this truck when it was a year old from a leasing company.
I got it for free a couple days ago,the PO was using it as his farm truck.
He had a ujoint blow on the rear diff and thought he had broke the tcase housing and didn't want to spend any money on it.
I took it because of the soft spot in my head for GM Diesels.
I crawled under it yesterday and there doesn't seem to be anything wrong with the tcase.
Funny how life turns out sometimes.I will fix the rear driveshaft and see what a freebee 6.2 runs like.
I have a off-road rescue mission that this truck may be the sacrificial 4x4 to do the job.
