We have to be sure where the noise is coming from, a advise you or ask someone to do the following tests:

  1. jack your both your rear tires and make sure its stable. turn your tires either manually or by shifting gear into reverse and try listening to any humming or whiny sound or vibration not only from your rear differentials but also your transmisssion and independent transfer case.
  2. Be sure it secured and will not move and will not squish you under.
  3. also check on your rear propellers, differentials for excessive play
  4. If you determined where it is coming from, check on your gear oils.
My own assesment from what you have just told us, is I would also check on your clutch system, because whiney noise only exist when you are backing up the car. I hope you would pin point which part is causing the whiney noise to save you all the headache of having it repaired.
Comment after you determine where it is coming from.
Thanks for dropping by fixya

Why rear wheels are locked up but front are not


the first place to check is then rear drive line "U" joints as fail on a regular basis and can be not allowing the shaft to turn properly
T check for diff , jack up one side and engage a gear
if the wheel spins then the diff is turning but if it makes a bad noise (all will rumble a t a low level in this position) the diff will be faulty
It is possible that a joint flange has come loose and the bolts are jamming on the back of the transfer case housing

HOW DO I CHANGE THE REAR WHEEL BEARINGS IN A 1993 JEEP GRAND CHEROKEE LARADO?


no they are bad, unless its brakes
a real mech , checks both.
its one or the other, or worse. bad axle gear/bearings/

the fsm covers both. ever seen the real book? on this car.
the ZJ book is here and free

http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service
posted like 100+ times, now......

keep in mind jeeps may have different axles.
2wd, 4wd, and locking axles (options)
models 30, 35 and 44 so the details vary that is why the book wins here. the real book wins.

diagnosis is an other matter, i have an electronic stethoscope
that allows me to drive and hear each bearing. cost me $35.

id inspect brakes first. after all they are in clear easy view.
make sure the brake parts are not seized. that includes
the Emg. brake parts !!!
does you car have ABS brakes?
some have drums others have rear disc brakes, the linked FSM
covers both.

for example disc calipers can fail in many ways
guides seized.
pistion seized
emg brake part stuck.
cracked rotors, or warped.

so that be first a real brake inspection on side that makes noise.

if the brakes are ok, then axle bearings are checked next
if you feel radial play they are BAD.
and more. ask.

Rough banging drive


if it's and SL or VR4 the carrier bearings on the propshaft( driveshave from front to rear on AWD) can get loose and cause a banging.
check for slop in the joints between the rear diff and the wheels. you really need to pull and push things around as hard as you can to find something loose enough. Also the whole rear diff is on a frame that hase bushings connecting it to the car so the busshings could have worn.
check the fluid in the rear diff for metal particles and make sure there's no slop in the diff. the propshaft going into the rear diff on the awd should have a small amount of play no more than 5mm.

4WD selected but only RWD active


Hi,
Your sami sounds as if the either the lockers, the axles or the transfer box are not doing too good... An open locker or a broken axle will steal all the power going to the front of the car. A transfer problem is also a good reason for this kind of thing, but this usualy happens with some noise, so you'd probably know if the transfer was bad. The front axle hub a.k.a. the diff can also be bad. I'd take off both lockers - 12 screws on each and a circlip (make sure they are in the free position ). You can now see the axles themselves and try to rotate them manually. While engaged in 4wd - they should not move more than a 1/4 turn. If both move free your diff or transfer box are bad, depending whether you see the front driveshaft moving or not. If drvshft is moving - transfer is bad. If not - the diff is gone. If only one is free - your axle is broken.  Not a biggie to diagnose but one hell of a pita to fix... I'd advise you to head to the shop and and have a pro fix it. Cheers emi

The rear problem with a 1999 gmc sierra truck


do you know if you have a limited slip rear diff?
if you do your grease is worn out or if the fluid was replaced it need to have a friction modifier put in the diff (can be found at any auto part stores.)

if its not a limited slip diff you might have spider gears going bad. then you need to remove the cover on the diff and inspect your spider gears2f73bce.jpg b440737.jpgand these are the spider gears
