NP242 Transfer Case Swap?

If you're fully locked Yes you can break a u-joint but it isn't 100% always going to happen. It takes many times for the ears on the shaft to stretch or break on the shaft which then takes out the u-joint. But how many times are you ever fully lock to lock when driving on the street?

Agreed x2

IIf you apply a lot of torque to the front at high speed and the steering wheel is turned to the maximum left for example, doesn't it breakthe ujoint? I thought that u-joints have issues at high angles at high speeds.

Yes they do have issues but at higher steering angles add some speed and it binds and like Wildman said,do it enough times and they'll break
That's why I snagged a set of cv shafts from a v8 Zj I believe ? You can get em at oreilys,they aren't Rcvs but they're cheap and pretty alright (they aren't "bulletproof" but they're technically stronger at full steering bump since they don't bind like a U joint shaft does)

Main reason I got them is that I can do better 4wd cyclones/donuts without breaking a joint (i almost did,the ujoint caps got loose) And I don't get annoying crow hop when crawling

This was from sawing the steering lock to lock and foot in the floor (V-8) with 38" tires and stock u-joints on Alloy USA shafts. They warrantied it and I put 300M u-joints in them then. But now I have RCV shafts. It was deep snow and I was working the steering trying to find some traction.

I have the tallest Jeep.... We were installing the trail sign.... It's called Leaning Tree... Like the Adopt A Highway program they do the same with trails and my club adapted it so we keep it cleaned up and clear of downed trees.

Don't know if I'll fit anymore.. I'm 6" wider now.

You would be rolling your jeep,not breaking a ujoint

Great scenario, impossible to accomplish. High speed and full lock don't happen.

I was gonna gonna say this but I didn't
Cause common sense lol

From the research I did Jeep used CVs on the early XJs with 242s but U-joints on the later ones. If Jeep was ok putting those on the street I think the few TJs that have actually been swapped with 242s will be ok too. I do have actual RCVs though.
