Pinion gear Thrust washer
18. Assemble the pinion gear:
18a. Press-in new bearings, if necessary.
18b. Apply some Durina grease to the shaft and the contact surfaces between the base of the pinion gear and
the thrust washer.
18c. Insert the shaft and washer from the inside of the housing.
18d. Install the shim washers and E-clip previously removed, then check end-play and run-out.
• Add shims to reduce end-play.
• Take-out shims to increase end-play.

16e. Inspect the shaft and bearings.
See Figure 5.76.
17. Final evaluation:
It may not be necessary to fully disassemble the tran-
saxle to identify the damage or find the root cause of a
warrantable failure.
At this point of disassembly, or some point earlier in the
process, the technician should be able to make an assess-
ment of whether it is feasible to repair the transaxle. It
should also be possible to positively identify what went
wrong in a warrantable transaxle replacement.
If the transaxle is to be warranted, reassemble it for
shipping. It may be called back for inspection.
If repair is feasible, proceed by the following steps:
19. Assemble and install the bevel gear shaft:
19a. Apply a small amount of anti-seize compound
to the splined section of the shaft.
19b. Slide the reverse gear, shift collar, and forward
gear onto the bevel gear shaft. See Figure 5.77.
NOTE: The gears are identical. Forward and reverse are
functional references. The reverse bevel gear is
nearest the reduction gear, while the forward gear
is nearest the brake rotor spline.
