Toyota Sienna Service Manual: Inspection

1. INSPECT SPIDER BEARING

(a) Check that the spider bearing moves smoothly by turning the flange.

(b) Check for the looseness around the joint by strongly moving the flange in the axial and radial directions.

HINT: If necessary, replace the shaft.

2. INSPECT INTERMEDIATE SHAFT

(a) Using a dial gauge, check for the swing of the intermediate shaft.

Maximum swing: 0.8 mm (0.031 in.)

NOTICE: The dial gauge must be set at right angles to the center of the intermediate shaft.

HINT: If shaft swing exceeds the maximum, replace the shaft.

(b) Using a dial gauge, check for the runout of the front side of the intermediate shaft flange.

Maximum runout: 0.1 mm (0.004 in.)

NOTICE: Ensure that the dial gauge is set at right angles to the measurement surface.

(c) Set a dial gauge outside the bolt hole on the rear side flange of the intermediate shaft, and check for runout in the horizontal direction.

Maximum runout: 0.1 mm (0.004 in.)

NOTICE: Ensure that the dial gauge is set at right angles to the measurement surface.

(d) Set a dial gauge to the circumference of the intermediate shaft flange, and check for runout in the vertical direction.

Maximum runout: 0.1 mm (0.004 in.)

NOTICE: Ensure that the dial gauge is set at right angles to the measurement surface.

HINT: If the intermediate shaft flange runout exceeds the maximum, replace the intermediate shaft.

3. INSPECT PROPELLER SHAFT ASSEMBLY

(a) Using a dial gauge, check for the swing of the propeller shaft assembly.

Maximum swing: 0.8 mm (0.031 in.)

HINT: If shaft swing exceeds the maximum, replace the propeller shaft assembly.

NOTICE: The dial gauge must be set at right angles to the center of the propeller shaft.

4. INSPECT CENTER SUPPORT BEARING ASSEMBLY NO.1

(a) Turn the bearing by hand with applying force in the direction of rotating. Check that the bearing turns smoothly.

(b) Check that the seals and bracket are not cracked or damaged.

HINT: If the bearing is damaged, worn, or does not turn smoothly, replace it.

5. INSPECT CENTER SUPPORT BEARING ASSEMBLY NO.1

(a) Inspect the center support bearing assembly No. 1 (rear) following the same procedures as for the center support bearing assembly No. 1 (front).

6. INSPECT PROPELLER SHAFT ASSEMBLY REAR

(a) Using a dial gauge, check for the runout of the rear propeller shaft assembly rear.

Maximum runout: 0.8 mm (0.031 in.)

HINT: If the shaft runout exceeds the maximum, replace the rear propeller shaft assembly rear.

NOTICE: The dial gauge must be set at right angles to the center of the propeller shaft.
