8.8 rear end in a jeep?

so i read somewhere that you could put a 8.8 inch rear end in a jeep wrangler. i was just wondering if anyone knew anything about this or have done this mod themselves.

I'm in the process of doing it now. What do you want to know? It's a very popular mod.

They're easy to find. I found my '00 Explorer rear end out of a V8 Explorer with a locker and disc brakes. It cost me $250. Now, you've gotta factor in the cost of the TJ suspension brackets. Those are going to cost you another $430. Save some labor expense and shave the 8.8's tubes yourself. Invest in a grinder and a SawZall with metal blades. They'll make short work of the Ford suspension brackets. They're thick, so it'll take a bit of time, but it's easy enough to do yourself. If you don't have a welder, you'll have to pay someone (with Jeep TJ knowledge) to weld up the new TJ suspension brackets on to your 8.8.........so factor in that extra cost. The good news is that you're getting a strong rearend that has disc brakes and will handle much bigger tires. There is a bunch of aftermarket support for the Ford 8.8, so bulletproofing it is as easy as shopping online. Oh yeah, the bolt pattern is the same as the TJ, so you won't have to buy new wheels.

-EDIT- I think it's the '95 and up models you're wanting. They have disc brakes.
Here's a pic of mine as it sits right now.......

I assume it's not worth it to make this switch with a D44 already installed?

A built 8.8 and a built D44 are going to be pretty comparable in strength. I hear of people running 37's on spooled stock 8.8s, so they might be a tad beefier.

No, the 8.8 is barely stronger than a D44 and that minor gain would not be worth the significant effort to get the 8.8 ready for mounting. Besides, you can simply drop in alloy 30 spline axle shafts into your D44 to be significantly stronger than the 8.8. And that still leaves 33 spline or 35 spline alloy axle shafts if you wanted your existing D44 to be even stronger.

Jerry, what's your opinion on the Superior Super 88 axle upgrade/c-clip eliminator for the 8.8? That's the route I'm planning on going with my 8.8........
