Trim lvl differences in axle/driveshaft cv/u joint

Does any body have any idea why some zj have cv style axles/driveshafts (like mine) and others have full u joints? Is it a trim level variance? I was wondering because my buddy has a 96 laredo just like mine but he has full u joints instead. Why would my particular 96 laredo have cv and his 96 laredo have u joints? I wa thinking maybe trim level variance because he has a sunroof and I don't and we both have NP249 transfer cases. Any ideas?

First, most of what your looking for is in the FAQ section. But part of the reason you find different axles is that people replaced them. My ZJ came with u-joints. I had a tough time trying to replace one of the u-joints (I don't have the tool or a press). So I just got a new CV joint axle. I may end up doing the same to the other side as that u-joint is starting to make some noise. The opposite is also true. Some with CV joints replaced them with u-joints because some people think they're better. The only way to know what you were supposed to have is with a build sheet.

Pretty sure this has been covered a few times, but to answer you -

If you have fulltime AWD you will have CVs. if you have the 242/231 you will most likely have ujoints. But as Pugulis mentioned, build sheet would be the most accurate way to know since most folks swap.

I searched. Not much came up. But no you didn't answer my question either. Lol. My post stated that we both have full time transfer cases, same 96 laredo. Only difference is he had a u joint axles and u joint driveshaft I have cv's................ Other than someone randomly swapping every axle AND driveshaft why would it come from the factory like that?

Searched the FAQ nothing was there about my question

Sorry about that, I thought there was info there. But, the reason for either cv or ujoint is not random. All 249's came from the factory with CV joints. Now, where it becomes confusing is that, I believe, at some point they completely stopped using u-joints. This is why there are many people that don't even think ZJ's came with them. And they talk about swapping in u-joints from an XJ. I think this happened in mid 96. Even, if this isn't true. While being assembled, if they run out of u-joints, they're not about to stop production when most vehicles are getting CV joints.

Did you both pull your build sheets to confirm that what is on the Jeep is original? And what I was saying (and Pugulis) is that someone could have swapped from CV's to U-joints. Pugulis has done the opposite. You don't need to swap drive shafts to swap the axles? Unless you are talking about something different.

the 249 always got cv axle from the factory. with u-joint shafts you get a really annoying feedback in the steering at higher turning angles. the 242 usually got u-joint axles.

drive shafts were usually v8 vs i6, but also they tended to use whatever they had laying around.
