2005 CHRYSLER CARAVAN service

(1) Remove the power steering pump from the
vehicle. Refer to Removal And Installation in this
section of the service manual.
(2) Remove the pulley from the shaft of the power
steering pump using Puller C-4333 (Fig. 14).
CAUTION: Do not hammer on power steering pump
pulley. This will damage the pulley and the power
steering pump.
(3) Replace pulley if it is found to be bent, cracked,
or loose.
ASSEMBLY - PUMP (PULLEY)
The only serviceable part of the power steering
pump is the pulley. The procedure following is for
removal and installation of the pulley from the pump
once the pump is removed from the vehicle.
(1) Install the pulley with Installer C-4063 (Fig.
15). Do not use the tool adapters.
(2) Ensure that the tool and the pulley remain
aligned with the pump shaft. Prevent the pulley from
being cocked on the shaft.
(3) Install the pulley until it is flush with the end
of the power steering pump shaft (Fig. 16).
(4) Install the power steering pump on the vehicle.

ment requires replacement of the piston assembly.
(45) Orient 2/4 clutch return spring to retainer as
shown in (Fig. 131), and install to transaxle (Fig.
132).(46) Using tool 5058, compress 2/4 clutch return
spring just enough to install snap ring (Fig. 133).
(47) Install snap ring.
(48) Set up dial indicator as shown in (Fig. 134)
and measure 2/4 clutch clearance. Press down on
clutch pack with finger and zero dial indicator.2/4
clutch pack clearance is 0.76-2.64 mm
(0.030-0.104 in.).Set up indicator and record mea-
surement in four (4) places. Take average of read-
ings. If clearance is outside this range, the clutch is
assembled improperly.There is no adjustment for
2/4 clutch clearance.

OPERATION
The differential assembly is driven by the transfer
shaft by way of the differential ring gear. The ring
gear drives the differential case, and the case drives
the driveshafts through the differential gears. The
differential pinion and side gears are supported in
the case by thrust washers and a pinion shaft. Dif-
ferential pinion and side gears make it possible for
front tires to rotate at different speeds while corner-
ing.
DISASSEMBLY
NOTE: The differential is serviced as an assembly.
The only parts that are serviceable within the differ-
ential are the differential bearing cups and cones. If
any other part fails within the differential, you must
replace the differential assembly along with the
transfer shaft.
The transfer shaft should be removed for differen-
tial repair and bearing turning torque checking.
(1) Remove the differential cover and bolts (Fig.
169) (Fig. 170).(2) Remove the differential bearing retainer and
bolts (Fig. 171) (Fig. 172).

NOTE: The differential is serviced as an assembly.
The only parts that are serviceable within the differ-
ential are the differential bearing cups and cones. If
any other part fails within the differential, you must
replace the differential assembly along with the
transfer shaft.
NOTE: Use MoparTATF RTV (MS-GF41), or equiva-
lent, on retainer and extension housing/adapter
plate to seal to case.
(1) Using Miller Special Tool L-4410, and C-4171,
install differential bearing to differential (extension
housing side) (Fig. 180).
(2) Using Miller Special Tool 5052 and C-4171,
install differential bearing to differential (bearing
retainer side).(3) Using Miller Special Tool 6061 and C-4171,
install differential bearing race to bearing retainer
(Fig. 181).
(4) Using Miller Special Tool L±4520 and C-4171,
install differential bearing cup to extension housing.
(5) Measure and adjust differential bearing pre-
load (Refer to 21 - TRANSMISSION/TRANSAXLE/
AUTOMATIC - 41TE/FINAL DRIVE -
ADJUSTMENTS) .
(6) Install differential assembly to case. Install
extension housing/adapter plate and bearing retainer.
