hi this is a question about a jeep cherokee. i live in england and have recently bought this car4.0 se 1994 model. the cars rear dif is wineing a bit how do i fix it before it compleatly goes.
it is still at the eary stage of going i think

 

dose it only do this when u turn and if so dose it have pose etraction?

 

no it does it when i press the accelerator as it speeds up if you take your foot off the accelerator it goes quiet

 

Either the differential is low on lube, check the fill hole,it should leak a little lube out when you take out the plug, or the backlash on the ring and pinion is off, this could be due to a worn pinion bearing, loose pinion nut (the big nut that holds on the driveshaft yolk to the diff ), or it could be worn parts in the rear end. The fact that the noise goes away when you let off the gas points to a little slop in the ring and pinion, if you're not a mechanic, checking those parts for proper tolerance is best left to a repair shop,or trusted mechanic friend.

 

if you take your foot off the accelerator and it goes away it is a tooth contact problem between your crown wheel and pinion you will need to strip your diff and replace your crownwheel and pinion or get them relapped

 

If your going to get a used one to replace it with look for one out of an 88' or 89' with tow package, they came with a Dana 44.

 

Ive got a Dana 44 on my 1955 Ford F100 with a 460ci(7.1L?) and it hasnt broken YET!

 

Yes, it does sound like some Ring and Pinion problems to me. But since it is a 1994 I would rule that out. Unless the cherokee has had a rough life. Then we have other problems. My 90 YJ with a D35 rear end has had no problems. I have not even snaped an axle shaft, but i keep waiting for it too [img]i/expressions/face-icon-small-happy.gif[/img].... If you do not plan on wheeling this jeep i would say dont get the D44, just get your D35 reworked.

I am not sure what an SE has on it. HAve you done any modifications to this Jeep? Is it an Auto or manual. Are you sure it is the rear diff?
