Toyota Sienna Service Manual: On-vehicle inspection
1. INSPECT REAR AXLE HUB BEARING BACKLASH
(a) Using a dial gauge, check for backlash near the center of the axle hub.
Maximum: 0.05 mm (0.0020 in.)
If backlash exceeds the maximum, replace the axle hub assembly.
NOTICE: Ensure that the dial gauge is set at right angles to the measurement surface.
2. INSPECT REAR AXLE HUB BEARING DEVIATION
(a) Using a dial gauge, check for deviation in the surface of the axle hub outside the hub bolt.
Maximum: 0.07 mm (0.0027 in.)
If backlash exceeds the maximum, replace the axle hub assembly.
NOTICE: Ensure that the dial gauge is set at right angles to the measurement surface.
