Dodge Dakota (R1). Manual — part 197

(3) Place Inclinometer 7663 (J-23498A) on yoke

bearing (A) parallel to the shaft (Fig. 8). Center bub-
ble in sight glass and record measurement.

This measurement will give you the transmis-

sion or Output Yoke Angle (A).

(4) Rotate propeller shaft 90 degrees and place

Inclinometer on yoke bearing parallel to the shaft
(Fig. 9). Center bubble in sight glass and record mea-
surement. This measurement can also be taken at
the rear end of the shaft.

This measurement will give you the Propeller

Shaft Angle (C).

(5) Subtract smaller figure from larger (C minus

A) to obtain Transmission Output Operating Angle.

(6) Rotate propeller shaft 90 degrees and place

Inclinometer on pinion yoke bearing parallel to the
shaft (Fig. 10). Center bubble in sight glass and
record measurement.

This measurement will give you the pinion

shaft or Input Yoke Angle (B).

(7) Subtract smaller figure from larger (C minus

B) to obtain axle Input Operating Angle.

Refer to rules given below and the example in (Fig.

11)for additional information.

• Good cancellation of U–joint operating angles

(within 1°).

• Operating angles less than 3°.

• At least 1/2 of one degree continuous operating

(propeller shaft) angle.

TWO-PIECE PROPELLER SHAFT

The procedure to measure the propeller shaft

angles involved with a two-piece (Fig. 12) propeller
shaft is the same as those for a one-piece propeller
shaft.

REMOVAL

(1) Position transmission and transfer case to their

neutral positions. Raise and support vehicle. Remove
skid plate, if equipped.

(2) Mark a line across the transfer case flange and

C/V for installation reference.

(3) Mark a line across the propeller shaft flange

yoke and front axle companion flange for installation
reference.

(4) Remove companion flange bolts (Fig. 13).
(5) Remove transfer case flange bolts and remove

propeller shaft.

INSTALLATION

(1) Install propeller shaft with with all reference

marks aligned.

(2) Loosely install bolts to C/V and transfer case

companion flange.

(3) Install bolts to companion flange and flange

yoke and tighten to 108 N·m (80 ft. lbs.).

(4) Tighten bolts to transfer case companion flange

to 30.5 N·m (22.5 ft. lbs.).

(5) Install skid plate, if equipped.
(6) Lower vehicle and road test to verify repair.

REMOVAL

(1) Place the transmission into the Neutral posi-

tion.

(2) Raise and support vehicle on safety stands.
(3) Mark a line across the axle companion flange

and flange yoke for installation reference.

(4) Mark an outline of the center bearing on the

support

bracket

installation

reference,

if

equipped.

(5) Mark an outline of the heat shield on the cen-

ter bearing for installation reference, if equipped.

(6) Remove center bearing and heat shield bolts, if

equipped.

(7) Remove companion flange bolts.
(8) Slide slip yoke off of the transmission, or trans-

fer case, output shaft and remove the propeller shaft
(Fig. 14).

INSTALLATION

(1) Slide the slip yoke onto the transmission, or

transfer case, output shaft.

(2) Align and install the center bearing and heat

shield to the support bracket, if necessary. Install the
bolts and tighten to 68 N·m (50 ft. lbs.).

(3) Align companion flange reference mark with

flange yoke mark.

(4) Install companion flange bolts and tighten to

108 N·m (80 ft. lbs.).

(5) Lower the vehicle.

CENTER BEARING

DESCRIPTION

The two-piece propeller shaft uses a center bearing

to support the shafts. The bearing is used to support
the shafts where they are joined together. The bear-
ing is insulated in rubber and is mounted to the
frame crossmember.

OPERATION

The propeller shaft center bearing serves to divide

the required propeller shaft length into two smaller
shafts, which has several inherent advantages. Hav-
ing two short propeller shafts instead of one long
shaft decreases the chance of unwanted noise and
vibrations. The shorter shafts are easier to balance
and serve to increase ground clearance while main-
taining acceptable driveline angles.

REMOVAL

(1) Remove rear propeller shaft.
(2) Remove slip joint boot clamp and separate the

two half-shafts.

(3) Use hammer and punch to tap slinger away

from shaft to provide room for bearing splitter.

(4) Position Bearing Splitter Tool 1130 between

slinger and shaft.

CAUTION: Do not damage shaft spline during
removal of center bearing.

(5) Set shaft in press and press bearing off the

shaft.

INSTALLATION

(1) Install new slinger on shaft and drive into posi-

tion with appropriate installer tool.

(2) Install new center bearing on shaft with Bear-

ing Installer Tool 6052. Drive on shaft with hammer
until bearing is seated.

(3) Clean shaft splines and apply a coat of multi–

purpose grease.

(4) Align master splines and slide front and rear

half-shafts together. Reposition slip yoke boot and
install new clamp.

(5) Install propeller shaft in vehicle.
