Ok so I got the parts ordered up here.

But now I am reading it's an easy swap to the 14 bolt diffs. Did those come with 3.42s? And what vehicle can I get them out of?

Ok so all the repair shops in the area are 2+ weeks out. I can't wait that long. I was quoted $750 for just the basic diff install.

My plan will be to tear it open on Tuesday, see if I can do the job myself.

If I can't, I am just going to get a junkyard one to get it back running.

14 bolts are on the 3/4 ton burbs and trucks. Leaf springs. Easy swap with a welder and fab shop! You would be bullet proof tho!

Called place and verified it's 14 bolt, 3.42 and 9.5 ring gear. Comes as entire axle assembly. I'd much rather do this, can have truck back on road by Monday rather than fiddling around with something I've never done before.

Ok so the 14 bolt is not a direct swap it seems you need a custom driveshaft.

I don't want to mess with all these unknowns..

So I either roll the dice and try to fix it with the truetrac

Or I just grab another junkyard 10 bolt to get it quickly back on the road.

Haha yup. The ring gear looked fine. I saw no cracks in the housing, all the fluid still there. I am going to just swap out the diff.

If I have trouble, then I will pickup a stock replacement since I now know they're readily available somewhat locally.

From what I read from randeez 14 bolt swap thread, he used a custom driveshaft. I don't want to mess with that, don't have time and can't risk it.

I thought I read somewhere they make conversion u-joints with different caps on the crosshairs to match what you are fitting together.
