Toyota Sienna Service Manual: Installation

1. INSTALL PROPELLER W/CENTER BEARING SHAFT ASSEMBLY

(a) Align the matchmarks on the propeller shaft assembly rear flange and differential companion flange, and connect the shaft with the 4 bolts, washers and nuts.

(b) Remove SST(s) from the extension housing.

(c) Insert the yoke into the extension housing.

NOTICE:

• Be careful not to damage the oil seal.
• Be careful not to damage the universal joint boot when installing the propeller shaft.

(d) Install the 2 adjusting shims and propeller shaft w/ center bearing, and loosely tighten the 4 bolts.

(e) Tighten the 4 nuts.

Torque: 74 N*m (750 kgf*cm, 54 ft.*lbf)

2. FULLY TIGHTEN PROPELLER W/CENTER BEARING SHAFT ASSEMBLY

(a) Remove the cloth from the joint.

(b) Using a hexagon wrench (6 mm), tighten the 6 bolts.

Torque: 29 N*m (296 kgf*cm, 21 ft.*lbf)

(c) With the vehicle unloaded, adjust the dimension between the rear side of the cover and shaft, as shown in the illustration.

(d) Adjust the front and rear dimensions between the edge surface of the center support bearing and the edge surface of the cushion to 12.5 +- 1.0 mm (0.492 +- 0.039 in.) respectively as shown in the illustration, then torque the bolts.

Torque: 37 N*m (375 kgf*cm, 27 ft.*lbf) (e) Check that the center line of the bracket is at right angles to the shaft axial direction.

(f) If any vibration or noise occurs, perform joint angle check as follows and replace the adjusting shim with a proper one.

(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.

(3) Remove the transfer dynamic damper.

(4) Using SST(s), measure the installation angle of the transfer extension housing (A) and front propeller shaft (B).

SST 09370-50010 No. 1 joint angle: A minus B = -0.4° to -1.6°

(5) Using SST(s), measure the installation angle of the rear propeller shaft (C) and rear differential (D).

SST 09370-50010 No. 2 joint angle: C minus D = -1.6° to -3.6°

If the measured angle is not within the specification, adjust with the center support bearing adjusting shim.

Center support bearing adjusting shim thickness

(g) Install the transfer dynamic damper.

Torque: 26 N*m (260 kgf*cm, 19 ft.*lbf)

3. INSTALL EXHAUST PIPE ASSEMBLY

(a) Install exhaust pipe assembly (See page EX-10).
