CAUTION:

For parts which are not reusable, always use new parts.
Always tighten the bushing in the state where the vehicle is at curb weight and the wheels are in full contact with the ground.
During the installation, make sure that the marking of ABS wheel speed sensor harness does not twist.

NOTE: This procedure is only for non-hybrid models. For hybrid models, perform the procedure by referring to the procedure for non-hybrid models.

Check the removed parts for wear, damage and crack, and repair or replace them if faulty.
