link bolt. Remove stabilizer bar clamp bolts. Remove stabilizer bar
and bushings. On Montero Sport remove the stabilizer link brackets and
bushings.
Installation
1) To install, reverse removal procedure. Note that slit in
stabilizer bushing faces vehicle. Marks on bar should be approximately
0.39" (10 mm) from edge of bracket. On Montero Sport adjust the
stabilizer link assembly mounting nut so there is 0.2-0.3" (6-8 mm) of
threads exposed from the top of the nut to the top of the threads.
TORSION BAR
NOTE: Mark torsion bar and anchor arm location for reassembly
reference before removing.
Removal
1) Raise and support vehicle. Support lower control arm using
jack stand. Loosen anchor arm adjusting bolt lock nut. Remove heat
protector from frame (right side only). Loosen anchor arm bolt to
release torsion bar tension.
2) Mark front of torsion bar and torque arm for reassembly
reference. Remove anchor arm. See Fig. 1. Remove dust covers from
torsion bar. Remove heat cover (right side only) located between dust
cover and torsion bar. Remove torsion bar.
Inspection
Inspect all splined areas for damage. Inspect dust covers for
cracks and damage. Check for bent anchor arm bolts. Replace components
as necessary.
Installation
1) Apply grease to splined areas of torsion bar, anchor arm,
torque arm splines, anchor arm bolt threads and inside of dust cover.
Check for left and right identification marks on torsion bar ends.
Ensure torsion bars are installed in correct locations.
2) Install torsion bar in torque arm, with identification
mark toward front of vehicle and the slit in the anchor collar facing
downward. Align mark on torque arm with mating mark on torsion bar.
When installing a new torsion bar, align White paint spline with index
mark on front anchor arm.
3) Tighten anchor arm bolt adjusting nut to obtain correct
final bolt protrusion. See FINAL ANCHOR ARM BOLT PROTRUSION table.
Final bolt protrusion depends upon curb weight of vehicle. With
vehicle unladen, measure distance from bump stopper bracket to bump
stopper. Distance should be 0.83-0.91" (21-23 mm) on Montero, 0.7" (18
mm) on Montero Sport. If not, adjust anchor bolt nut.

nut. Tighten shock absorber upper nut until distance from end of
threads to nut is 0.04-0.08" (1.0-2.0 mm) on vehicles with standard
shock absorbers, and 0.06-0.10" (1.5-2.5 mm) on vehicles with Variable
Shock Absorbers. Install lock nut.
3) Tighten bolts to specification. See TORQUE SPECIFICATIONS.
Bleed brakes. Adjust anchor arm bolt to proper torsion bar setting.
See TORSION BAR under REMOVAL & INSTALLATION. Check wheel alignment,
and adjust it if necessary. See WHEEL ALIGNMENT SPECIFICATIONS &
PROCEDURES article in WHEEL ALIGNMENT section.
WHEEL BEARING
Removal
Raise and support vehicle. Remove wheel assembly. Remove axle
hub. See AXLE HUB under REMOVAL & INSTALLATION. Clean any grease from
the inside surface of the front hub. Drive out the inner and outer
bearing races by tapping them uniformly using brass drift and hammer.
Installation
Lubricate bearing races. Install bearing races in hub using
Handle and Bearing Installer (MB990938 and MB990935). Ensure bearing
races are fully seated. To complete installation, reverse removal
procedure. Adjust wheel bearing preload. See WHEEL BEARING under
