Yupp. I use 75-140. Front and rear.

 

Looks like I ll have to do that. The rear axle is on it's way out.

 

I have a 8.25 from a 96 xj. Going to throw it into my new 96 xj that has the 35. Is it going to be worth throwing it in? I have heard that I want the 8.25 from a 97xj+ because it has 29 spline.

I guess I'm just asking if it will be worth my time to drop it in. about 250k on the 8.25 axle. Thoughts or opinions?

 

If I recall correctly they changed the splines in 96.

 

So I could potentially have a 29 spline down there? Personally I have never messed with the diffs and only have basic mechanical knowledge. So any advice ahead of time would be awesome.

 

I would say to pop off the diff cover and count splines

 

That's what I'll have to do. I'm doing some reading on another site and they are in an argument that early 96 models came with 27 whilst the later models came with 29. I'll pray for a later model but with my luck I'll have 27.

I'll report back with findings.

 

I'm running 30x9.50" tires with a 2.5" coil and full leaf lift. I'm about to put 31x10.50 BFG a/t on stock steel wheels will I have any rubbing issues

 

Yes, the front tires will rub the lower control arms at full steering lock.

 

I was worried about that, ok thanks

 

Some rims will fix that up in a jiffy. Spacers are technically an option but you must be vigilant about keeping them torqued properly and buy quality units in the first place. Although for how much a good set of spacers are worth you might as well get rims.

More lift won't do much since the control arms will still be in the same spot, laterally speaking.

 

What's the minimum backspacing I could get away with

 

My 87 Cherokee 4 liter auto won't start. It turns over and starts when I spray ether but then dies immediately. Is there a fuse or relay for the fuel pump? What color wire is it to power it on? It runs down the driver side next to the drivers seat, correct?

 

Won't start at all without starting fluid?

There is a fuel pump relay and a fuel pump ballast resistor.

 

Alright guys I've got a 89 xj 4.0 with the auto trans but when i put it in drive it goes straight to overdrive but shifts fine if i put it in first manually. What could be the problem?
