2002 CHRYSLER CARAVAN shaft

When turning corners, the outside wheel must
travel a greater distance than the inside wheel to
complete a turn. The difference must be compensated
for to prevent the tires from scuffing and skidding
through turns. To accomplish this, the differential
allows the axle shafts to turn at unequal speeds (Fig.
39). In this instance, the input torque applied to the
pinion gears is not divided equally. The pinion gears
now rotate around the pinion mate shaft in opposite
directions. This allows the side gear and axle shaft
attached to the outside wheel to rotate at a faster
speed.
FLUID - DIFFERENTIAL
ASSEMBLY
STANDARD PROCEDURE - DIFFERENTIAL
ASSEMBLY FLUID DRAIN AND FILL
The drain plug (Fig. 40) for the differential assem-
bly is located in the bottom of the differential assem-
bly case, toward the rear of the unit.
The fill plug (Fig. 41) for the differential assembly
is located on the rear of the assembly case.
The correct fill level is to the bottom of the fill plug
hole. Be sure the vehicle is on a level surface, or is
hoisted in a level manner, in order to obtain the cor-
rect fill level.
(1) Raise the vehicle on a hoist.
(2) Position a drain pan under the differential
drain plug (Fig. 40).
(3) Remove the drain plug and allow the fluid to
drain into the pan.
(4) Install the drain plug and torque to 35 N´m (26
ft. lbs.).
(5) Re-position the drain pan under the differential
fill plug.
(6) Remove the differential fill plug (Fig. 41).

(2) Remove rear wheel and tire assemblies from
vehicle.
(3) Remove the caliper to adapter guide pin bolts
(Fig. 23).
(4) Remove rear caliper from adapter using the fol-
lowing procedure. First rotate front of caliper up
from the adapter. Then pull the rear of the caliper
and the outboard brake shoe anti-rattle clip out from
under the rear abutment on the adapter (Fig. 24).(5) Support caliper to prevent the weight of the
caliper from damaging the flexible brake hose (Fig.
25).
(6) If the brake rotor needs to be removed it can be
removed by removing the retainer clips and then
pulling the rotor straight off the wheel mounting
studs.
(7) Remove the outboard brake shoe from the cali-
per. Brake shoe is removed by pushing the shoe
toward the piston, disengaging the two metal protru-
sions on the shoe back, then sliding the brake shoe
off the caliper.
(8) Remove inboard brake shoe from caliper.
Inboard brake shoe is removed by pulling it out of
the caliper piston, until the retaining clip is free of
the piston (Fig. 26).
