1991 DRIVE AXLES
Locking Hubs
Mitsubishi: Montero, Pickup
DESCRIPTION
Automatic hubs are engaged by rotational force of axle shaft
when 4WD is selected at transfer case. Automatic hubs disengage when
2WD is selected or vehicle is driven in Reverse. Cams, brakes and
springs are used to lock or unlock automatic hubs.
Engagement is accomplished through gears and spring actions
within hub. When hub is locked, hub brake engages inner hub, which is
connected to axle shaft by inner splines of hub. Hub brake is
connected to hub body by outer splines.
REMOVAL
1) Hub must be unlocked. To unlock hub, place transfer case
lever in 2H position and move vehicle in Reverse approximately 4-6
feet.
2) Remove cover from locking hub. If hub cover cannot be
loosened by hand, wrap shop towel around cover and use an oil filter
wrench to loosen cover.
3) Raise and support vehicle. Remove wheel assembly. Using
snap ring pliers, remove snap ring and shim from end of axle. Remove
locking hub retaining bolts. Remove locking hub.
INSTALLATION
1) To install, reverse removal procedure. Apply sealant to
contact areas between locking hub assembly and hub/rotor assembly.
Ensure sealant is NOT applied on outer areas of hub/rotor assembly
toward brake contact areas.
2) Align locking hub assembly key area with steering knuckle
key way area. Loosely install locking hub assembly on hub/rotor
assembly. Ensure locking hub assembly fully contacts hub/rotor
assembly.
3) Install locking hub retaining bolts. Tighten bolts to 36-
43 ft. lbs. (49-58 N.m). Using spring scale attached to wheel stud,
measure turning resistance required to rotate hub/rotor assembly.
4) Turning resistance should NOT exceed 3.1 lbs. (1.4 kg). I\
f
turning resistance exceeds specification, check for incorrect
installation of locking hub assembly or components.
5) Install shim and snap ring on drive axle. Rotate drive
axle until maximum end play is obtained. Using a dial indicator, check
drive axle end play.
6) Drive axle end play should be .008-.020" (.20-.51 mm). If\
axle end play is NOT within specification, adjust end play by changing
axle shaft shim. Install hub cover. Tighten hub cover 13-25 ft. lbs.
(18-34 N.m).
