Fig. 6: Installing New Front Axle Shaft Seal
AXLE SHAFT OVERHAUL
NOTE: All front axle shafts except (Select-Trac) use Cardan "U"
joints and should be overhauled in same manner as drive
shaft "U" joints.
DISASSEMBLY (SELECT-TRAC)
1) Cut and remove both outer boot clamps. Slide boot off
outer CV joint.
2) Using a block of wood seated on inner race, tap joint from
shaft. If shaft is clamped in a vise, be sure to use protective vise
jaws.
3) Tap outer CV cage with a brass punch until cage is tilted
Page 378 of 1378
out far enough to remove first ball bearing. Remove remaining ball
bearings in same manner.
4) Rotate outer CV joint cage outward until it is at a 90
degree angle to installed position. Align 2 oblong holes in outer
joint cage with slots in interior wall of spindle housing and remove
cage and inner race.
5) Remove inner race from cage by aligning shoulder between
race grooves with inside of oblong cage holes. Rotate inner race out
of cage using larger of 2 openings in cage. Remove retaining ring,
spacer ring and outer boot.

CLEANING & INSPECTION
1) Wash all parts in solvent and dry. Inspect inner and outer
ball races for damage. Inspect splined stub shaft for wear, cracks and
twisted splines.
2) Inspect all 6 balls for pitting, cracking or scoring.
Dulling of surface is normal. If any damage is found, replace entire
CV joint assembly. Polished areas in races and on cage spheres are
normal and DO NOT require joint replacement.
REASSEMBLY
1) Apply a light coat of CV grease on ball grooves of inner
and outer races. Install inner race into cage using a rotating action
opposite of removal. Inner race snap ring should face axle side.
2) Be sure ball bearing retaining ring is installed on inner
race side facing small end of cage. Align windows of cage with outer
race lands, and pivot cage with inner race into tilted position
(opposite of removal).
3) Install ball bearings one at a time into outer CV joint as
cage is tilted and rotated. After balls are installed into cage, pivot
cage and inner race into installed position.
4) Slide new seal clamp for small end of boot seal, boot seal
and seal retainer onto axle shaft. Coat inside lip (large diameter end
of seal) with CV grease. Slide seal retainer on end of seal.
5) Spread ears of bearing race snap ring, and slide CV joint
onto axle shaft until snap ring seats in groove. Pack joint with
approximately 1/2 of grease provided in seal kit. Apply remaining
grease inside seal.
6) Slide seal toward joint until small end of seal is in
groove in axle shaft. Position small clamp over small end of seal and
into groove and tighten.
