It's not that hard to convert as long as you are comfortable swapping an axle and transmission and have a decent set of tools.

better reserve a couple days, stack up on tools, replacement bolts, and beer. Also make sure you get the right driveshaft too!

or..

I would just buy one with 4x4, just my 2 cents.

Can't think of any special tools. Is your MJ an auto or manual?

Hopefully both are 4.0L auto? Then it's easy (XJ front bolts in, but the rear doesn't) I use a come-along to pull the front axle back to put the bolts in. 15 mm heads will drive you crazy. The track bar bottom bolt tends to strip out. If you have access to 3 /12" taller or at least 4x4 front coils, it helps to do it now. You can do the front axle one weekend, then the trans/tcase the next. Check the gear ratio because most 4.0L autos are 3.55 ratio, but may be different and you need a match for 4x4.

What is the difference in a 4.0 auto and manual front end? I have a 91 Comanche 2wd with aw4/np232 already installed. Have a donor 87cherokee 4x4 with 5 speed. I plan to put the Cherokee axle in the Comanche. Is there a difference in axle/cases? Thanks

The front axle itself will be the same auto or manual. But the gear ratio may be different. Spline count on the transfer case may be different. I believe the Renix AW4s use a 21 spline transfer case.

Thanks, the aw4 is from a newer Cherokee and I have to put 5:56 gears in it anyway to match the rear. Thanks for the info. Looks like I'll only be needing a driveshaft.
