FRONT AXLE HUB INSTALLATION

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.

Tech Tips

Use the same procedure for the RH side and LH side.
The following procedure is for the LH side.
