That and I'm pretty sure that the 4.0 with 300,000 miles on it wouldn't last long. Im looking for something to get it up in the air. That and being its my dd I need something I can do in a weekend. Rockwells and a motor and trans swap a little longer then a weekend to do. I understand that the d35 are a weak axle. But then I also ran 36s with a d28 in a ranger for 2 years wheeling every weekend. I only ever busted the stock hubs got a set of mile markers never had a problem. No disrespect to anyone it's just not the info I was looking for. I didn't wanna buy the lift tires and not be able to get everything done in a weekend. That and a buddy of mine built the axles so I know the parts ain't cheapo crap. That and before I put the rockwells under anything I'm going to spend some cash on them more then likely what I paid for the jeep the cost of the lift and tires. That and they will be going under my 88 bronco 2 project I have.
1. 8" is plenty to clear 38s, especially if you don't mind trimming. There are plenty of people out there running 38s on half that lift.
2. The 300k on the 4.0 is no big deal unless it's been trashed and no ones changed the oil on it. My first XJ had 380k on it when I sold it and it ran like it was brand new. Hell, there's a guy out in CO that's got 650k on his original 4.0 and trans and all he's ever done is basic maintenance.
3. People are telling you you can't run 38s on a d35 for a reason. They're notorious for being weak and I wouldn't even run 33s on one. You WILL break it if you do any remotely serious wheeling on it. Anything short of a halfway built D44 and 8.8 isn't going to handle 38s for long.
If not wasting money is an issue trying to put an 8" lift and 38s on in a weekend let alone on stock axles is downright stupid.
Even aside from the lift and tires you're still going to need drive shafts, SYE, wheels, almost entirely new steering components, regeared axles, brakelines, ect.
If you want to slap a lift and tires that on something in a weekend and go wheel it get rid of the XJ and go buy a full size truck or SUV.
