Insert pinion gear and washers (in same position it was removed) into final drive. Check chalk or crayon mark.
Important:
Make sure the pinion gear is installed the same way that it was removed. If the gear is installed upside down, it may cause a
noise because of the change in set wear pattern.

IMPORTANT:
Make sure there are no extra needle bearings left after replacing washers. There must be no spaces between needle
bearings. Check for pinion end play.
Do not install more than the required amount of washers (4) per each pinion (2 on each side of pinion) into the final drive.
