PROPELLER SHAFT
PROPELLER SHAFT (Continued)
The propeller shaft front segment utilizes a plung-
ing CV joint at the PTU flange, and a plunging CV
joint at the center bearing location. These joints are
flexible, allowing for torsional movement of the pow-
ertrain.
The propeller shaft center and rear segments uti-
lize a support bearing/bracket, which support this
three-piece assembly and isolates driveline vibrations
from the body. The rubber coupler at the driveline
module flange dampens out propeller shaft torsional
vibrations, as the driveline module it connects to is
fastened to the rear suspension crossmember.
REMOVAL
CAUTION: Propeller shaft removal is a two-man
operation. Never allow propeller shaft to hang from
the center bearing, or while only connected to
power transfer unit (PTU) or rear driveline module
flanges. A helper is required. If a propshaft section
is hung unsupported, damage may occur to the
joint, boot, and/or center bearing from over-angula-
tion. This may result in driveline vibrations.
(1) Raise vehicle on hoist.
(2) Remove hanger at rear muffler.
(3) Remove exhaust system center hanger brackets
(Fig. 3) and support exhaust system with screw jack.
(4) Make sure transaxle is in neutral (N). Using
chalk, mark propeller shaft flanges at PTU and rear
driveline module for installation reference.
(5) Remove six propeller shaft-to-power transfer
unit bolts (Fig. 2), but do not remove from PTU at
this time.
NOTE: Rubber coupler is part of the propeller shaft
assembly. Removing coupler from propeller shaft
will result in vibration/balance issues.
(6) Remove three propeller shaft rubber coupler-to-
driveline module bolts, but do not remove from driv-
eline module at this time.
(7) Have helper support front segment by hand
while removing center segment bearing/support-to-
body bolts. Support front and center segments by
hand (Fig. 3).
(8) While manually supporting front and center
segments, have helper support rear segment while
removing rear segment bearing/support (Fig. 3).
(9) Lower propeller shaft assembly to ground,
using care not to damage fore and aft flanges (Fig.
3).
INSTALLATION
CAUTION: Propeller shaft installation is a two-man
operation. Never allow propeller shaft to hang while

connected to power transfer unit (PTU), rear driv-
eline module flanges or center bearings. If propeller
shaft section is hung unsupported, damage may
occur to joint, boot and/or center bearing from
over-angulation. This may result in vibration/bal-
ance issues. A helper is required.
(1) Make sure transaxle is in Neutral (N) position.
(2) Obtain a helper and lift propeller shaft assem-
bly into position (Fig. 3). Load shaft to driveline mod-
ule first, and then PTU flange.
(3) Install center and rear support bearing/bracket
assemblies into position. Install bolts hand-tight.
(4) Align paint index marks at driveline module
flange and install three propeller shaft rubber cou-
pler-to-rear driveline module bolts by hand. Torque
propeller shaft rubber coupler-to-rear driveline mod-
ule assembly bolts to 54 N·m (40 ft. lbs.).
(5) Align chalk index marks at PTU flange. Install
six propeller shaft-to-PTU flange bolts (Fig. 2) and
torque to 30 N·m (22 ft. lbs.). Torque bolts alternately
to ensure proper flange mating.
(6) Place center and rear bearing/supports into
position. Install and torque support/bearing-to-body
bolts to 54 N·m (40 ft. lbs.).
(7) Raise exhaust system into position. Install
muffler rear hanger. Remove support stand.
(8) Install exhaust system center hanger
(9) Lower vehicle.
