Maximum: 0.05 mm (0.0020 in.)
If backlash exceeds the maximum, replace the bearing.
NOTICE: Ensure that the dial gauge is set at right angles to the measurement surface.
2. INSPECT FRONT AXLE HUB BEARING DEVIATION
(a) Using a dial gauge, check for deviation in the surface of the axle hub outside the hub bolt.
Maximum: 0.05 mm (0.0020 in.)
