Got a 3.5" RE lift and 31x10.50s. Been feeling slight vibrations from the tcase whenever i let off the gas. I did notice that the handle for 4wd sometimes vibrated and made noise at idle when not in 2wd and would go away when i just touched it or moved it slightly. I got the tcase drop and plan on putting it on today or tommorrow. But the question is I on the beach yesterday (ive driven on the beach tons of times w/ no problems) and yesterday I was in low (pretty damn soft/deep spot by my house) and i had 2 friends with me and i heard a thud and fwd was gone. Stopd... put it in neutral and put it into hi. It worked for a few seconds and then a thud again and no fwd. Was like screw it, went surfing and got a guy to yank me cuse the rear had dug a bit. When he did this all the sudden my 4wd worked flawlessly again.

Any ideas? I'm dropping it off tonight to get it looked at, would be nice if i could point the guys in a direction maybe.

thanks,
Creighton

 

hmm, your driveline angles should be ok. Do you have a 231 or a 242? Whens the last time you changed the fluid in the t-case? I would go ahead and put some new fluid in.

 

im assuming you have a vacuume operated differential disconnect... (since its a newer cherokee) you could have had a problem in the lines and it cleared its self.. i lost mine on my toyota once... and got stuck.. just had to splice them back together and it fixed the problem.

 

i know the driveline angle is off, I am putting in a tcase drop tonight (1"). Ya, its a 231 as well. I'm thinking it was cuse I did hit some really deep sand and deep ruts and the rear end sat more w/ 2 more people in the car w/ all the boards and shit in the rear and it slid out, then slid back in once i got yanked? shrug.

only fluids ive changed is oil... bought it from a dealership about 12k miles ago.

 

Stop touching yourself at night and the jeep would be ok.

 

Now, why didn't I think of this?!?

 

is the 4wd shift linkage all lined up i know thats why i lost my 4wd bc i hit a stick and bent the shift linkage. i could use 4low but not 4hi. check that may be that may not. ask the guys over at www.jeepforums.com they know jeeps like the back of there hand.

 

ya, I visit naxja.org for info. i'll check it out. got a guy lookn at my jeep tommorrow (inspection, oil pump and scopin out the tcase).

if nothings outa the ordinary ill start lookn for obscure things like you mentioned.

thanks

 

what did you find out

 

from what I can tell its just the driveline angle due to the lift. got the spacer on the tcase and all is fine... just slipped out temp. I assume from bouncing in the sand.

Eventually I'm gonna get a slip yolk eliminator and a shaft to fix that problem the correct way.
