FRONT AXLE HUB ON-VEHICLE INSPECTION

CAUTION / NOTICE / HINT

Note


  • When removing or installing the front disc brake caliper assembly, pushing back the disc brake piston may cause a large clearance between the brake pads and brake disc. When the brake pedal is depressed with a large clearance between the brake pads and the brake disc, DTCs C1214 related to abnormal brake fluid pressure may be stored. Make sure to clear DTCs after performing this step.

  • While the auxiliary battery is connected, even if the power switch is off, the brake control system activates when the brake pedal is depressed or any door courtesy switch turns on. Therefore, when servicing the brake system components, do not operate the brake pedal or open/close the doors while the auxiliary battery is connected.

Tech Tips


  • Use the same procedure for the RH side and LH side.

  • The following procedure is for the LH side.

PROCEDURE

  6. INSPECT FRONT AXLE HUB BEARING LOOSENESS


    1. A01MJA2

      Using a dial indicator, check for looseness near the center of the front axle hub sub-assembly.

      Maximum Looseness
      0.05 mm (0.00197 in.)

      Note


      • 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.

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

  7. INSPECT FRONT AXLE HUB RUNOUT


    1. A01MHJ2

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

      Maximum Runout
      0.05 mm (0.00197 in.)

      Note


      • 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.

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