BACK-UP LAMP SWITCH
REMOVAL
(1) Raise vehicle on hoist.
(2) Disconnect back-up lamp switch connector.
(3) Remove back-up lamp switch (Fig. 95).
INSTALLATION
(1) Install back-up lamp switch (Fig. 95) and
torque to 23 N´m (17 ft. lbs.) using Tool 8827.
(2) Connect back-up lamp switch connector.
(3) Lower vehicle.
DIFFERENTIAL
DESCRIPTION
The T850 differential is a conventional open design.
It consists of a ring gear and a two-piece differential
case. The differential case contains the pinion and side
gears, three floating pinion shafts, and a pinion shaft
retaining ring (Fig. 96). The differential case is sup-
ported in the transaxle by tapered roller bearings.
OPERATION
The differential assembly is driven by the interme-
diate shaft via the ring gear. The ring gear drives the
differential case, and the case drives the halfshafts
through the differential gears. The differential pinion
and side gears are supported in the case by pinion
shafts and thrust washers. Differential pinion and
side gears make it possible for front wheels to rotate
at different speeds while cornering.
DISASSEMBLY
(1) Remove differential side bearings:
(a) Install button 8491-1 to differential case (Fig.
97).(b) Set up Tool 5048 (5048-1, -4, -6) as shown in
(Fig. 98).
(c) Remove differential side bearing (Fig. 99).
Same procedure/tools work for both sides.

(9) Install differential support plate. Align support
plate to differential case with alignment pins 8470
(Fig. 118).
(10) Install thrust buttons 8491 to both bearing
journals and press halves together using an arbor
press (Fig. 119).(11) Install ring gear into position, start three ring
gear-to-differential case bolts by hand (120É apart),
and install alignment pins 8470 (Fig. 120).
(12) Torque three ring gear bolts to draw ring gear
into position. Remove alignment pins, install remain-
ing ring gear-to-differential case bolts and torque to
95 N´m (70 ft. lbs.) (Fig. 121).
