Pinion Seal
Drive Pinion Bearing Shim Selection
This procedure must be performed whenever the drive pinion spacer has been replaced.
Fig. 37
(1) Using a one inch micrometer, measure the thickness of the original spacer (Fig. 37).
(2) Measure the thickness of the new spacer the same way that the original spacer was measured.
(3) The difference in the measurements of the old spacer and the new spacer will determine which shim to use.
(4) If the new drive pinion spacer is the same thickness as the original, use the original shim.
(5) If the new drive pinion spacer is thinner than the original drive pinion spacer, a thicker shim must be used. This will compensate for the difference
in size.
(a) Determine the difference in size between the new spacer and the original spacer. Record this dimension.
(b) Measure the thickness of the original shim,
Record this dimension.
(c) Add together the two dimensions recorded in steps (a) and (b). Use a new shim that is equal to this size.
For Example: The new spacer is 0.010 thinner than the original spacer. The original shim measures 0.205. Adding 0.205 and 0.010 equals a
new shim thickness of 0.215.
(6) If the new drive pinion spacer is thicker than the original drive pinion spacer, a thinner shim must be used. This will compensate for the difference
in size.
(a) Determine the difference in size between the new spacer and the original spacer. Record this dimension.
(b) Measure the thickness of the original shim.
Record this dimension.
(c) Subtract the dimensions recorded in step (a) from the dimension recorded in step (b). Use a new shim that is equal to this size.
For Example: The new spacer is 0.010 thicker than the original spacer. The original shim measures 0.205. Subtracting 0.010 from 0.205 equals
a new shim thickness of 0.195.
Drive Pinion Seal and/or Rear Overrunning Clutch Seal
The rear drive line module must be removed to service these seals. The drive pinion seal is located in the front carrier cover, behind the overrunning
clutch rear seal. The overrunning clutch seal must be removed to gain access to the drive pinion seal. Do not reuse overrunning clutch seal.
REMOVAL
(1) Remove rear drive line module from vehicle.
