Well after replacing BOTH CV axle shafts. and trouble shooting i cant seem to find out whats clicking with my 4X4! i am driving a 1994 jeep zj and my 4wd works (to an extent it seems to to slowly dying) but my issue is when it gets put into 4 wheel it clicks badly, it does not click when driving down the road unless i let off the gas and if im offroad and push the accelerator it clicks horribly, i was planning on going home and removing the front drive shaft, putting her in 4 and seeing seeing if the issue is something up front but before i do so do you think this could just be a transfer case bearing? any input appreciated thanks you very much. (expecting a response from you dave) haha

Clicking to me sounds like ujoints, in either the front drive shaft or axle.

Jeez Ryan, it's one thing after another with you, isn't it? If the clicking is not rhythmic and is coming from the t/case, I suspect a worn chain skipping over drive teeth. There are several good YouTube videos on changing it. You can do it without pulling the case out.

(edit) i accidentally said drive shafts not axle shafts my bad. how much would a chain run? and the names Noah haha

dave1123

Okay Noah! My bad. rockauto.com has them for about $100. The only REAL way to tell if it's bad is to pull the rear case half and see. If caught soon enough, the drive sprockets should be fine. The only hard part about the repair is a couple of PITA snap rings and getting it sealed up again.

Never done work on the T-case before but when i go in to the shop on tuesday to help my engine builder with tearing down his zj i will have him help me out with it, its def. something i want to get fixed because the trails are embarrassing when im clicking my way through! although i probably shouldn't be using it in the shape its in i cant resist. 100$ is pretty spendy for me atm trying to save up for this engine im getting but i guess its worth it.

You WERE waiting for my response, weren't you? I spent about an hour looking at those videos because I was curious myself. My WJ has about 187K on it, mostly road miles, and I was curious if mine was worn, but I'm not showing any problems, YET! I'm conscience of this problem because my brother broke a chain in his Blazer and it destroyed the case! (NP208)

what had me stumped is the fact that it only clicks at lower speeds, during a turn or if to much pressure is applied. if im cruising down the road it works perfectly fine! a tranny and T case upgrade is in the making but that's later this year/early next summer depending on what all i do to my engine this spring. trying to get my drivetrain all sorted out before i go forward with a better lift. and yes i was waiting for your response! i always expect you see you here in the GC threads!

Wait!....I'm confused. What vehicle are we talking about? I thought it was only clicking in 4wd. You have a 242 t/case, right?

Okay, rereading the original post shows a 94 ZJ. It MAY be front axle u-joints. Going straight they won't make noise, but in a turn, especially under power, they can click, squeak, or cause wheel hopping and binding. The u-joints are only about $10 each and are easy to replace. They are not greaseable in assembly, so make sure they are full when you put them in. DON'T rely on the packing grease only.

I sometimes get confused talking to so many guys. I got you confused with Clayto and his WJ engine problems. I'll try not to jump in until my brain is engaged. LOL!

Yes only in 4wd does it bind/click, although! it will "pop" if i go around a corner with a steep drop or incline like exiting a gas station or entering a out of level driveway.

dave1123

Okay, forget what I said about the u-joints if you've got CVs. It still sounds like the t/case to me. The chain came to mind because of it's age.

BRAIN FART!!! How about the front driveshaft splines? My Chevy truck's front shaft splines were worn out causing vibration and popping when in 4wd. Just an idea.

Haha all the struff i have tried troubleshooting this past week, i guess its one of those things im gonna need to tear down to find out, hopefully tomorrow or Tuesday i can find some time.

CV joints will click when turning, sometimes only in reverse or only forward, generally heard when slow and power applied. It's quite common on fwd cars to hear snd diagnose, I'd guess it would react the same while in 4wd. Either way will be looking to see what you find.
