INSTALLATION

PROCEDURE

1. TEMPORARILY TIGHTEN PROPELLER WITH CENTER BEARING SHAFT ASSEMBLY

(a) When reusing a propeller with center bearing shaft assembly and rear differential carrier assembly: (1) Align the matchmarks on the rear differential carrier assembly and propeller with center bearing shaft assembly. (2) Temporarily install the 4 nuts and 4 washers. NOTICE: Do not apply grease to the 4 bolts, 4 nuts or 4 washers.

*a Matchmark

(b) When using a new propeller with center bearing shaft assembly or rear differential carrier assembly: (1) Align the alignment marks on the rear differential carrier assembly and propeller with center bearing shaft assembly. (2) Temporarily install the 4 nuts and 4 washers. NOTICE: Do not apply grease to the 4 bolts, 4 nuts or 4 washers.

*a Alignment Mark

(c) Align the matchmarks on the transfer 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 2 bolts and 2 center No. 2 support bearing washers (for front side). NOTICE: Reuse the center No. 2 support bearing washers. Do not apply grease to the bolts and 2 center No. 2 support bearing washers.

*1 Center No. 2 Support Bearing Washer

(f) Temporarily install the propeller with center bearing shaft assembly with the 2 bolts and 2 center No. 2 support bearing washers (for rear side). NOTICE: Reuse the center No. 2 support bearing washers. Do not apply grease to the bolts and 2 center No. 2 support bearing washers.

*1 Center No. 2 Support Bearing Washer

(g) Fully tighten the 4 nuts. Torque: 35 N·m {357 kgf·cm, 26 ft·lbf}

(h) Fully tighten the 4 nuts. Torque: 35 N·m {357 kgf·cm, 26 ft·lbf}

2. FULLY TIGHTEN PROPELLER WITH CENTER BEARING SHAFT ASSEMBLY

(a) 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):

11.3 to 13.3 mm (0.445 to 0.524 in.)

(b) Fully tighten the 2 bolts (for front side). Torque: 36.8 N·m {375 kgf·cm, 27 ft·lbf}

(c) Fully tighten the 2 bolts (for rear side). Torque: 36.8 N·m {375 kgf·cm, 27 ft·lbf}

(d) Check that the center line of the bracket is at a right angle to the shaft axial direction.

3. INSPECT AND ADJUST JOINT ANGLE

NOTICE:

Measure the joint angle when the vehicle is raised using a four-post lift or when using a pit.

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 joint angles.

(1) Check the No. 1, No. 2 and No. 3 joint angles.

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

SST: 09370-50010

Joint Angle:

(3) Check the No. 4 joint angle.

*a No. 4 Joint Angle (D - E)

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

SST: 09370-50010

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.
