4. INSPECT FRONT AXLE HUB BEARING LOOSENESS

(a) Using a dial indicator with magnetic base, check for looseness near the center of the front axle hub sub-assembly.

Maximum Looseness:

0.05 mm (0.00196 in.)

NOTICE:

Ensure that the dial indicator is set perpendicular to the measurement surface.
Keep the magnet of the dial indicator away from the front axle hub sub-assembly and front speed sensor.

HINT:

If the looseness exceeds the maximum, replace the front axle hub sub-assembly.

5. INSPECT FRONT AXLE HUB RUNOUT

(a) Using a dial indicator with magnetic base, check for runout on the surface of the front axle hub sub-assembly outside the front axle hub bolts.

Maximum Runout:

0.05 mm (0.00196 in.)

NOTICE:

Ensure that the dial indicator is set perpendicular to the measurement surface.
Make sure to set the tip of the dial indicator towards the outside of the front axle hub bolts.
Keep the magnet of the dial indicator away from the front axle hub sub-assembly and front speed sensor.

HINT:

If the runout exceeds the maximum, replace the front axle hub sub-assembly.
