90-863160 MAY 2000
a. Mount retainer wrench in vise to support U-joint assembly.
b. Position U-joint assembly so that shaft is pointing straight down.
a - Torque Wrench (lb-in.)
b - U-joint Shaft (Hanging Straight Down)
c. Set preload by tightening nut 1/16 of a turn at a time. Check for proper preload by
turning pinion gear, using an extension, appropriate socket, and torque wrench (lb-
in. - with dial indicator), until a 6-10 lb-in. (0.7-1.1 Nm) torque is obtained. If nut be-
comes over-tightened (causing excessive preload), loosen nut a number of turns
and lightly strike pinion end of U-joint shaft using a soft hammer. Readjust, starting
at beginning of this step.
