Need a diagram or information on how to replace Rear end....Making loud scrubbing noises and will not shift into reverse now!

could be internal piston housing failure for the bands
pull the pan and see what metal is in the pan
there is an aluminium housing that breaks away from the transmission body proper and is replaceable

What most people see as a harsh transmission shift when transitioning from forward gears to reverse gear is really just the drive train taking up the slack in the connections. You need to realize that over time the universal joints in the drive shaft, as well as the pinion and ring gears in the rear differential will experience wear. When you are going forward the drive shaft is turning one direction, the u-joints and differential gears are all taking stress one one particular side. When you shift to reverse, everything reverses. So, the first thing to happen is the front u-joint changes direction. There will be a small amount of slack in the joint from wear. This slack will cause an irregular motion while it is taken up. This irregular motion is propagated to the rear u-joint, which must do the same. It will induce additional irregular motion, which is passed to the pinion and ring gears in the rear differential. In a new car/truck, you won't hardly notice this since all the wear surfaces are new and at factory tolerances. Give the vehicle 60-100K miles or more of hard wear and the result of this shifting to reverse can be a relatively loud clunking noise that can shake the vehicle. Replacement of u-joints can alleviate some of the issue, but the rear end wear can only be addressed with replacement. But as we say.....if it ain't really broke, why fix it?

sounds like rear end is coming apart
google wrangler forums and post there

CK THE U JOINTS ON THE DRIVE SHSFT. YOU HAVE TO REMOVE THE SHAFT AND SEE IF THE JOINTS MOVE SMOOTHLY. IF NOT REPLACE THEM. ALSO CK THE CENTER SUPPORT BEARING IF IT HAS ONE. ALSO CK THE TRANS MOUNTAND THE FLUID LEVEL IN THE REAR END. HOPE THIS HELPS BILL

This will help.

Thanks.

Rear end is a lockup dif. This couples both wheels.It has clutches that allow inner and outer weels to turn at different speeds when going around corner, thus eliminating most tire scrub. If noise is coming from dif. change dif oil and redress clutches.Driving in a straight line with a lockup dif. would not normally be noticed,because both rear wheels are travelling at the same speed.

universal joints clunk,is it in the rear end then maybe it is the rear end.you kinda need to be more specific if this information doesn't help

Removal Procedure Tools RequiredJ 38400
Caution: Keep fingers away from rear brake shoe springs to prevent fingers from being pinched between spring and shoe web or spring and backing plate.

1. Remove the brake drum. Refer to Brake Drum Replacement
