U-joints are stronger than CV joints, and u-joints are replaceable. CV joints run a little bit smoother, which is desirable for Full-Time 4x4 equipped Jeeps. Given a choice, most off-road users would probably choose to have u-joints.

excellent. i will swap to the u joint style shafts, because i dont think i will use full time 4x4 much. it doesnt snow here and we dont get too much rain, so the only 4x4 modes i would be using is part time and low.

i seem to remember reading that some XJs came with bigger u joint on the axle shafts? if so, which ones was it? id love to upgrade from stock ZJ ones if the XJs are better.

CV's are plenty strong, the only advantage on the axles is that you have a chance of repairing the shaft on the trail.

I'm not a fan, for dd uses I keep cvs on both jeeps. I love full time 4wd, even on dry pavement there is a difference in handling for the better.

Maybe I'll change my tune after I snap a shaft on the trail, maybe.

One of my CV's let go on me yesterday. I wasn't even wheeling either, just turning to back into my parking spot :'(

Luckily, I got it on camera (in jeep cam)

I ran CVs even with the crate 5.9. It's what you want to run. Most run CVs and never have and issue with them.

Doin a swap on the trail isn't bad (happened to me last year). I didn't know s*** about how to pull it out but was with a great group of guys and we stopped and pulled out the shaft and then I drove/got pulled out in 3wd But at least I made it out. Mine is a AT-4wd so I like the cv's since it's my dd. I am going to start wheeling more so maybe I'll end up swapping them after i break 3 or 4 cv's lol.

After pulling myself together I decided to go see what kind of scraps I could find and what it looked like underneath

It's a 96 ZJ limited. Would anyone be able to tell me if I'm going to find C-clips, or will I just be able to slide the axle shaft out?

Just a friendly reminded, don't drive it til you at least see if you can pull the shaft (seriously pull the hub and if the shaft doesn't come out with relative ease, well someone else is gonna have to chime in). Don't wnat to mess up the spider gears or anything.

It's pretty easy to swap the cv shaft.

Pop the wheel off, pull the caliper off the knuckle (2x13mm bolts), pull the rotor off (falls off after the caliper is off), pull the cv shaft nut (35 or 36mm, factory is 36 but many aftermarket are 35), pull the three hub bolts (funny 12pt heads), may have to pull the abs sensor to get the shaft out, but it just pulls out.

Be careful putting the new shaft in not to damage the oil seals at the diff.

Reverse puts it back together. Knuckle to hub bolts get 75 ft lbs, axle nut gets 175 ft lbs.
