U-joints vs. CV joints

I posted this question in the "non-tech section" and it got moved to the "other tech" section, which might as well be a banishment :bawl:. I know someone on here knows the answer as it could apply to an XJ with the 242 transfer case as well:

Got a '96 Grand Cherokee with the 5.2 in it for a good price. The owner tells me the VC in it has been replaced, but when I turn the wheel hard I can feel wheel hop like its in 4wd. I've been told that it could just be U-joints that cause that (apparently some ZJs came with CV joints up front) and the putting CV joints on will cure it.

Sound right to anyone? It needs a new tranny, and I'm wondering if I should just hook up a 231 t-case or maybe a 242 t-case.

Yeah its full-time four wheel drive.

May have a bad CV Joint. Check for play.

I'am not sure what T-Cases will work with this trans.

Good Luck
Nick

If it's got Ujoints in the front axle, that could be the reason for a slight wheel hop at low speeds.

Without a doubt I would throw a different Tcase in there if at all possible. Why would you want to use a Tcase that is known for expensive failures of the VC??

yeah, I have a '93 ZJ with 318 V8 and I got it with a broken front CV and I swapped out the axle shafts with some ujoint shafts and it binds when turning at low speeds - I am swapping in a NP231 - the only thing I dont know it the length of the input shaft which I won't know until I take the case out and if its different I have to order the correct length or if mines too long I can cut it down :skull1:

231 or 242 will swap in, although you will need to swap the input shaft from the 249 into the 231 or 242.

yes, and you have to watch out for the change in the "gear cut" in the early 90's I can't remember when the change was but it is sort of a gray area

If he gets one out of a 95 or above XJ there won't be a problem. Probably even prior to 95 too but I'm not sure about the gear cut change either.
