oil or ATF from leaking.
B: INSTALLATION
1) Insert the sleeve yoke into the transmission and
attach center bearing to body.
Tightening torque:
52 N
⋅
m (5.3 kgf-m, 38.3 ft-lb)
2) Align the matching marks and connect the flange
yoke and rear differential.
Tightening torque:
31 N
⋅

3) Install the heat shield cover.
4) Install the center exhaust pipe.
5) Install the rear exhaust pipe and muffler.
6) Lower the vehicle.
7) Connect the battery ground cable to battery.
C: INSPECTION
NOTE:
Do not disassemble propeller shaft. Check the fol-
lowing and replace if necessary.
• Tube surface for dents of cracks
• Splines for deformation or abnormal wear
• Joints for non-smooth operation or abnormal
noise
• Center bearing for free play, noise or non-
smooth operation.
• Oil seals for abnormal wear or damage
• Center bearing for breakage
Check the following points with propeller shaft in-
stalled in vehicle.
1. JOINTS AND CONNECTIONS
1) Remove the center exhaust pipe.
2) Remove the heat shield cover.
3) Check for any looseness of the flange yoke
mounting bolts which connect to rear differential
and center bearing bracket mounting bolts.
2. SPLINES AND BEARING
1) Remove the center exhaust pipe.
2) Remove the rear exhaust pipe and muffler.
3) Remove the heat shield cover.
4) Turn the propeller shaft by hand to see if abnor-
mal free play exists at splines. Also move yokes to
see if abnormal free play exists at spiders and
bearings.
3. RUNOUT OF PROPELLER SHAFT
1) Remove the center exhaust pipe.
2) Remove the rear exhaust pipe and muffler.
3) Remove the heat shield cover.
4) Set the dial gauge with its indicator stem at cen-
ter of propeller shaft tube.

Service limit 0.6 mm (0.024 in)
4. CENTER BEARING FREE PLAY
1) Remove the front and center exhaust pipe.
2) Remove the rear exhaust pipe and muffler.
3) Remove the heat shield cover.
4) Move the propeller shaft near center bearing up
and down, and left and right with your hand to
check for any abnormal bearing free play.

A: REMOVAL
1) Disconnect the ground cable from battery.
2) Lift-up the vehicle and remove the front wheels.
3) Unlock the axle nut.
4) Remove the axle nut using a socket wrench
while depressing the brake pedal.

nut. Failure to follow this rule may damage the
wheel bearings.
5) Remove the stabilizer link.
6) Remove the disc brake caliper from housing,
and suspend it from strut using a wire.
7) Remove the disc rotor from hub.
NOTE:
If the disc rotor seizes up within hub, drive disc rotor
out by installing an 8-mm bolt in screw hole on ro-
tor.
8) Remove the cotter pin and castle nut which se-
cure tie-rod end to housing knuckle arm.
9) Using a puller, remove the tie-rod ball joint from
knuckle arm.
10) Remove the ABS wheel speed sensor assem-
bly and harness.
