CALIPERS
You are not required to replace or rebuild calipers in axle
sets. However, when replacing or rebuilding a caliper due to the
conditions that follow, you may suggest servicing, rebuilding, or
replacement of the other caliper (on the same axle) for improved
performance and preventive maintenance (for example, the part is close
to the end of its useful life, replacing the caliper may extend pad
life, or contribute to more balanced braking).
CAUTION: When installing loaded calipers, it is required that
friction material be matched in axle sets for consistent
braking characteristics.

INSTALLATION
1) If oil seal replacement is necessary, install new oil seal
in differential carrier using Oil Seal Installer (MB990934-01) and
Handle (MB990938-01). Coat seal lips with grease. Install housing
tube. Using Seal Installer (MB990955) and Handle (C-4171), install n\
ew
dust seal in housing tube. Dust seal must be even with housing tube.
Coat seal lip with grease.
2) Using a pipe with O.D. of 2.95" (74.3 mm), wall thickness\
of .16" (4.0 mm) and with overall length of 1.97" (50.0 mm), install\
dust cover on shaft. Coat inside of dust cover with grease. Press
bearing on shaft. Install new circlip on inner shaft. Drive inner
shaft into differential. Use care not to damage oil seal.
DRIVE AXLES & BEARINGS OVERHAUL
NOTE: References to BJ refer to Birfield Joint and DOJ to Double
Offset Joint.
DISASSEMBLY
1) Remove boot bands. Remove circlip from DOJ outer race.
Separate drive axle from DOJ outer race. Remove balls from DOJ cage.
Remove DOJ cage from DOJ inner race in direction of BJ. See Fig. 2.
Fig. 2: Exploded View of Drive Axles

2) Remove snap ring from drive axle shaft. Remove DOJ inner
race from shaft. Remove circlip from shaft. Wrap tape around splines
Page 262 of 1333
of shaft to prevent boot damage during removal.
3) Remove DOJ boot. Note size of boot. Remove dust cover from
shaft. Straighten BJ boot protector and remove protector band. Move
boot protector toward BJ side of shaft and remove. Remove BJ boot.
CAUTION: Drive axle and BJ are serviced as a unit. DO NOT
disassemble BJ and drive axle.
REASSEMBLY
1) Coat shaft with light coat of grease. Wrap splines with
tape. Install BJ boot, bands and DOJ boot on shaft. Ensure correct
size boot is installed in proper location.
2) Boot bands must be installed so lever is pulled toward
rear of vehicle when band is tightened. Pack proper amount of grease
in BJ and BJ boot. See GREASE APPLICATION table.
3) Place DOJ cage on shaft with smaller diameter installed
first. Install circlip, DOJ inner race, and snap ring on shaft. Apply
grease to DOJ inner race and cage. Install balls into cage.
4) Apply proper amount of grease to outer DOJ race. Install
shaft into DOJ outer race. Apply proper amount of grease to DOJ outer
race and install circlip. See GREASE APPLICATION table.
5) Place DOJ boot over DOJ outer race. Install boot bands so
lever is pulled toward rear of vehicle when band is tightened. Adjust
DOJ boot bands to have proper distance between centerline of boot
bands. See BOOT BAND SPECIFICATIONS table. This distance is necessary
to control air in DOJ boot. Tighten boot bands.
6) Install boot protector and band. Install dust cover on
shaft. Use a pipe with O.D. of 2.68" (68.0 mm), wall thickness of .09"\
(2.3 mm) and with overall length of 6.70" (170.1 mm) to install dust\
cover.

TESTING & INSPECTION
AXLE SHAFT END PLAY
Using dial indicator, check axle shaft end play. End play
must be .0020-.0079" (.05-.20 mm). If end play is not within
specification, change shims to obtain correct end play. See AXLE
SHAFTS under REMOVAL & INSTALLATION.
AXLE TOTAL BACKLASH
1) Raise and support rear axle. Place transmission in
Neutral. Apply parking brake. Rotate drive shaft clockwise. Place
reference marks on pinion dust cover and differential housing.
2) Rotate drive shaft counterclockwise and measure distance
between reference marks. Differential must be removed and backlash
adjusted if distance exceeds 0.2" (5.0 mm).
LIMITED SLIP DIFFERENTIAL PRELOAD
1) Place transmission in Neutral. Block front wheels. Raise
one rear wheel free of ground and remove wheel. Use Axle Puller
Adapter (MB990241) for Montero and Pickup models. Install adapter on
wheel studs. Release parking brake.
2) Using torque wrench, measure starting torque on Pickup
models while rotating wheel in forward direction. On Montero models,
measure rotating torque. This measurement is read once axle is
turning. Differential must be repaired if torque is less than
specification. See TESTING SPECIFICATIONS table.
