I have a 1993 Jeep Grand Cherekee Laredo 5.2 LT. V-8 4X4 with a Quadra-Trac 4 WD type system. This as you may know is all the time 4 WD. As I begin to turn my steering sharply to the left or right, there begins a very noticeable popping/wobbling/binding sounds from the rear of the vehicle. I've drained and replaced both front and rear diff. oil with mobil synthetic 75w140 as recommended by my dealer. I also replaced the transfer case oil with ATF 4 trans. fluid as an eliminater to the noise. What can be the cause of these noises from the rear. It seems like a wheel is wobbling as I turn sharply. The jeep has 240,000 miles and I've owned it since 18,000 miles

Did you add any limited slip additive to the axles, when you changed the fluid? Did you inspect the gears inside the rear end?

Reply to Brian W.'s Post: All fluids were changed front & rear diff. Both diffs. looked very good inside, no metel shavings were visible from pan removal. Chrysler told me it did not have limited slip, however I put 4 oz. of chrysler additive to the rear diff only.

You have tapered roller bearings at the ends of the axle housing. I have a 2002 and mine makes noise getting off an exit ramp.


The bearings and a retainer sleeve are pressed on the rear axle shaft, so you will need to find someone with a press if you plan to do-it-yourself.


AXLE SHAFT SEAL AND BEARING


REMOVAL



  1. Remove axle shaft from vehicle

    NOTE: It is normal that the axle bearing race is loose in the axle tube.


  2. Remove the studs from the axle retaining plate.
  3. Using a 3/8 in. dia. drill bit, drill a shallow hole into soft steel axle bearing retaining ring If possible, use a drill depth stop to avoid marking axle.
  4. Using a suitable cold chisel, cut retaining ring across drilled hole.
  5. Slide retaining ring from axle shaft.
  6. Using Splitter 1130 placed between the seal and bearing and a suitable Arbor Press, press bearing from the axle shaft
  7. Slide seal from axle.
  8. Slide retaining plate from axle shaft.

INSTALLATION



  1. Using a suitable straight edge, verify flatness of axle shaft retaining plate. Replace plate if warped.
  2. Install the studs back into the retaining plate. If the studs are loose in the plate, replace the retaining plate.
  3. Install retaining plate on axle
  4. Apply a coat of multi-purpose grease on sealing surface of axle seal.
  5. Install seal on axle with cavity away from retaining plate
  6. Lubricate bearing with Mopar® Wheel Bearing Grease, or equivalent. Wipe excess grease from the bearing.
  7. Slide bearing onto axle shaft
  8. Using Installer 7913 and shop press, press bearing onto axle shaft
  9. Using Installer 7913 and shop press, press soft metal retaining ring onto axle shaft
  10. Install axle in vehicle.
