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.
