Cougar/XR7 V8-4.6L VIN W (1997)
2. Remove the drive pinion bearing adjustment shim from the drive pinion.
NOTE: Measure the drive pinion bearing adjustment shim, which is found under the differential pinion bearing, with a micrometer and record the
thickness. Use this as a reference to compare the shim gauge reading before installing the bearing.
3. If replacing the differential pinion bearings, tap alternately (with a brass drift of suitable length) on each side of the differential bearing cup during
removal to prevent differential bearing cups from cocking in the carrier bore. Remove differential bearing cups.
NOTE: To make sure bearings are properly seated, clean bores before installing differential pinion bearings.
4. Complete disassembly by performing Differential Case Runout Check.

DRIVE PINION SHIM SELECTION
Perform Drive Pinion Shim Selection procedure before begining assembly. See: Pinion Gear/Adjustments
PINION BEARING & CUP INSTALLATION
1. Install new differential drive pinion bearing cups with Pinion Bearing Cup Replacer T71P-4616-A. Make sure differential drive pinion bearing
cups are properly seated in their bores. If a 0.038 mm (0.0015 inch) feeler gauge can be inserted between differential drive pinion bearing cup,
differential drive pinion bearing cup is not properly seated.
NOTE: When replacing differential drive pinion bearing cups also replace differential pinion bearings.
DRIVE PINION SEAL INSTALLATION
NOTE: The same differential pinion bearing used in this procedure must be used in final assembly of the rear axle assembly:
