REMOVAL 1. Remove the front propeller shaft assembly by removing the
four bolts.
INSTALLATION 1. Confirm the installation indicating mark on the front differen
tial attaching surface ofthe front propeller shaft.
2. Confirm the installation indicating mark on (painted with pink) the front propeller shaft attaching surface ofthe front differential companion flange.
3. Install the propeller shaft in such a way that the installation indicating mark ofthe front propeller shaft may be lined up with the installation indicating mark of the front differential companion flange. CAUTION: o If this operation should fail to be performed correctly, the
propeller shaft may emit abnormal noise or vibration.
4. Install the front propeller shaft assembly with the tour bolts,
four spring washers, tour nuts and then, tighten the nuts.

Case where propeller shaft is reused
REMOVAL 1. Remove the front propeller shaft by removing the four bolts.
CAUTION: e Prior to the removal, mating marks should be put on each of the flange yoke and companion flange of the front differential. If this operation should fail to be performed, the propeller shaft may emit abnormal noise or vibration during the running.
INSPECTION 1. With a dial gauge placed at the center of the propeller shaft,
measure the runout.
Allowable Runout Limit: 0.5 mm (0.020 inch)
Replace to the new front propeller shaft, if the runout is exceed than 0.5 mm (0.020 inch)
2. Check to see if any damage is present at the seal of the
spider section of the universal joint.
3. Check the flange yoke and sleeve yoke.
(1) inspect to see if any damage is present at the differen
tial drive pinion companion flange-contact section (D. (2) Check the oil seal sliding section for damage or wear. (3) Check the spline for damage or wear. (4) Fit the sleeve yoke onto the sliding spline of the trans
mission output shaft. Ensure that the spline exhibits no looseness inthe rota- tion direction andthe sleeve can slide freely in the axial direction on the spline.
INSTALLATION
1. Apply gear oil to both the inner and outer sides of the
propeller shaft sleeve.

Install the propeller shaft with the mating marks that were put during the removal of the propeller shaft aligned with each other.
Tightenlng Torque:
6.0 - 8.0 kg-m (43.4 - 57.9 ft-lb, 58.8 - 78.5 N-m)
CAUTION: o Make sure to line up those mating marks that were put during the removal of the front propeller shaft. If this caution should fail to be observed, the propeller shaft may emit abnormal noise or vibration.
REPLACEMENT OF UNIVERSAL JOINT SPIDER SUBASSEMBLY (FRONT)
Move the center of the propelier shaft in up-&-down and rignt~&-left directions so as to check the universal joint spider for excessive play by hand feeling. NOTE: The removal procedure for the universal joint spider subassembly is the same both at the sleeve yoke side and at the flange yoke side. Therefore, the procedure for the sleeve yoke (at the differential side) only is described here.
Remove the front propeller shaft by removing the four bolts, CAUTION: o Prior to the removal, mating marks should be put on each of the flange yoke and companion flange of the front differential. v If this operation should fail to be performed, the propeller shaft may emit abnormal noise or vibration during the running.
Put different paint mating marks on the propeller shaft and each of the yoke side sections (universal joint sleeve yoke subassembly and universal joint with flange yoke). (The illustration in the right figure indicates an example of mating marks.) CAUTION: v lf this operation should fail to be performed, the propeller shaft may emit abnormal noise or vibration during the running..

Set a new universal joint spider to the universal joint sleeve yoke. Temporarily install new universal joint spider bearing cups (two pos.) to the universal joint with flange yoke, by pushing them with fingers.
install the right and left universal joint spider bearing cups, using the foliovving SST.
SST: 09520-87604-OOO
NOTE: ~ Be sure to evenly press the right and left cups, until you can see the snap ring attaching groove provided on the outer periphery surface of the universal joint spider bear- ing cup.
Temporarily install the universal joint sleeve yoke subas- sernbly to the propeller shaft. CAUTION: ~ Be sure to align the paint marks (at the propeller shaft and sleeve yoke sides) which were put before the removal with each other. If the mating marks described above are not aligned with each other, it may cause abnormal vibration or abnormal noise of the propeller shaft. - Make sure that the grease nipple faces toward the
propeller shaft side.
