INSTALLATION

PROCEDURE

1. TEMPORARILY TIGHTEN PROPELLER WITH CENTER BEARING SHAFT ASSEMBLY

(a) Remove SST from the transfer assembly.

(b) Insert the propeller with center bearing shaft assembly into the transfer assembly.

(c) Align the matchmarks on the electro magnetic control coupling sub-assembly and propeller with center bearing shaft assembly.

*a Matchmark

(d) Temporarily install the 4 nuts and 4 washers. NOTICE: Do not apply grease to the 4 bolts, 4 nuts or 4 washers.

(e) Temporarily install the propeller with center bearing shaft assembly with the 4 bolts, and 4 center No. 2 support bearing washers. NOTICE: Reuse the center No. 2 support bearing washers. Do not apply grease to the 4 bolts or 4 center No. 2 support bearing washers.

(f) Fully tighten the 4 nuts. Torque: 73.5 N·m {749 kgf·cm, 54 ft·lbf}

2. FULLY TIGHTEN PROPELLER WITH CENTER BEARING SHAFT ASSEMBLY

(a) Remove the piece of cloth or equivalent from the universal joint flange.

*a Piece of Cloth

(b) Using a 6 mm hexagon socket wrench, fully tighten the 6 cross groove joint set bolts.

Torque:

26 N·m {265 kgf·cm, 19 ft·lbf}

(c) With the vehicle unloaded, adjust the distance (A) between the rear side of the cover and shaft as shown in the illustration. Distance (A): 65.5 to 70.5 mm (2.58 to 2.78 in.)

(d) With the vehicle unloaded, adjust the front and rear distance (A) between the edge surface of the center No. 2 support bearing assembly and the edge surface of the cushion respectively as shown in the illustration, and then tighten the bolts.

Distance (A):

11.5 to 13.5 mm (0.453 to 0.531 in.)

(e) Fully tighten the 4 bolts. Torque: 36.8 N·m {375 kgf·cm, 27 ft·lbf}

HINT:

If any vibration or noise occurs, perform the joint angle check as follows and replace the center No. 2 support bearing washers with ones of the correct thickness.

(a) Stabilize the propeller shaft and differential.

(1) Turn the propeller shaft several times by hand to stabilize the center support bearings.

(2) Using a jack, raise and lower the differential to stabilize the differential mounting cushion.

(b) Check the No. 1 and No. 4 joint angles.

(1) Using SST, measure the transfer assembly installation angle (A) and propeller shaft assembly installation angle (B).

SST: 09370-50010

No. 1 Joint Angle:

(2) Using SST, measure the rear propeller shaft assembly installation angle (C) and rear differential carrier assembly installation angle (D).

SST: 09370-50010

No. 4 Joint Angle:

If the measured angle is not within the specified range, adjust it with center No. 2 support bearing washers.

(c) Adjust the No. 1 joint angle and No. 4 joint angle.

(1) Select center No. 2 support bearing washers for adjustment.

Center No. 2 Support Bearing Washer Thickness:
