the sensor becoming inoperative.
1. Remove wheel bearing lock nut.
2. Remove brake caliper assembly and rotor.
Brake hose need not be disconnected from brake caliper.
In this case, suspend the caliper assembly with a wire so as
not to stretch the brake hose.
Be careful not to depress the brake pedal, to prevent the
piston from popping out.
Make sure brake hose is not twisted.
3. Separate tie-rod from knuckle with tool.
Install stud nut inverted on stud bolt to prevent damage to
stud bolt.
4. Remove kingpin cap and securing nut. Separate kingpin from
