2. LOOSEN CROSS GROOVE JOINT SET BOLTS
(a) Depress the brake pedal and hold it.
(b) Using a SST, loosen the cross groove joint set bolts
1 /2 turn.
SST 09313±30021
HINT: Put a piece of cloth or an equivalent into the inside of
the universal joint cover.
REMOVAL OF PROPELLER SHAFT
1. DISCONNECT FRONT PROPELLER SHAFT
(a) Place the matchmarks on the both flanges.
(b) Remove the four bolts, washers and nuts.
3. REMOVE INTERMEDIATE SHAFT AND REAR
PROPELLER SHAFT
(a) Place the matchmarks on the both flanges.
(b) Remove the bolts, nuts and washers.
(e) Remove the two bolts, front center support bearing and
washers.
(d) Remove rear center support bearing and washers. (c) Pull the yoke from the transfer.
(d) Insert SST in the transfer to prevent oil leakage.

INSPECTION OF PROPELLER SHAFT
1. INSPECT PROPELLER AND INTERMEDIATE SHAFTS
RUNOUT
If shaft runout is greater than maximum, replace the shaft.
Maximum runout: 0.8 mm (0.031 in.)
2. INSPECT INTERMEDIATE SHAFT FLANGE RUNOUT
(a) Inspect the front side of intermediate shaft flange run-
out.
Maximum runout: 0.1 mm (0.004 in.)
(b) Inspect the rear side of intermediate shaft flange
runout in vertical direction.
Maximum runout: 0.1 mm (0.004 in.)
3. INSPECT SPIDER BEARINGS
Check the spider bearing axial play by turning the flange
while holding the shaft tightly.

DISASSEMBLY OF PROPELLER
SHAFT
1. REMOVE REAR CENTER SUPPORT BEARING
(a) Using a hammer and chisel, loosen the staked part of
the nut. 4. INSPECT CROSS GROOVE JOINT
Check the joint smooth play by turning the joint in directions
as shown. And check the crack or damage or grease leak-
age of boot. If problem is found, replace the joint.
(d) Using SST, remove the rear flange.
