GENERAL TROUBLE SHOOTING section.
REMOVAL & INSTALLATION
AXLE SHAFTS R & I
Removal
1) Raise and support vehicle. Remove wheels and undercover.
Ensure hub is in free-wheeling position. Place transfer case in 2H
position. Remove drive hub cover, snap ring and shim from axle shaft.
See Fig. 3 . Remove brake calipers and support aside.
2) Disconnect tie rod assembly. Support lower control arm
with jack. Separate ball joints from knuckle. Remove knuckle and front
hub assembly. Using flat-blade pry bar, carefully remove left axle
shaft from differential carrier. DO NOT damage oil seal. On right axle
shaft, remove axle shaft-to-inner shaft flange retaining bolts. Remove
right axle shaft.
CAUTION: Replace circlips on BJ/DOJ splined shaft end.
Installation
1) Install right axle shaft on inner shaft flange. Install
new circlip on DOJ side of left axle shaft. Carefully install left
axle shaft into differential. DO NOT damage oil seal.
2) Reinstall knuckle with front hub assembly. To complete
installation, reverse removal procedure. Install shim and snap ring.
Check axle end play. See Fig. 4. End play should be .016-.028" (.4-.7
mm). If end play is not within specification, install correct shim.
