11. Do not back off the wheel bearing nut.
Notice: DO NOT use a rigid feeler gauge or a wire spark plug gap gauge to set the wheel speed sensor to tone wheel air gap as these tools will not
result in the correct air gap.
12. Insert flexible shim stock or equivalent between the tone wheel (1) and the wheel speed sensor (4).
