Steps
Loosen the axle and wheel nuts
With the vehicle on the ground, remove the center cap and loosen the axle nut and wheel nuts slightly. Do not loosen the axle nut with the vehicle raised unless the service procedure permits it.
Raise and support the vehicle
Lift the front corner at an approved point and support it securely on a jack stand. Remove the wheel and finish removing the axle nut, keeping the axle threads protected.
Remove the brake assembly
Remove the caliper fasteners and support the caliper with a hook or bungee so its hose is not stretched. Remove the bracket and pads, then remove the rotor retaining screw and lift off the rotor.
Disconnect the ABS sensor and hub
Remove the ABS sensor fastener and carefully withdraw the sensor without twisting its wire. Remove the hub mounting bolts from behind the knuckle and work the hub free while supporting the axle.
Install the replacement hub
Clean corrosion from the axle splines and knuckle mounting face. Position the new hub squarely on the axle, align its connector, and tighten the mounting bolts to the manufacturer's specification.
Reinstall the sensor and brakes
Refit the ABS sensor and route its wire in the original retainers. Reinstall the rotor, bracket, pads, and caliper, lubricating only approved pad contact points and keeping grease off friction surfaces.
Torque the axle and wheel
Install and tighten the axle nut to the vehicle specification using a calibrated torque wrench; do not rely on impact tightening. Reinstall the wheel, torque its fasteners in a star pattern, and confirm the ABS wire and brake hose are clear.
Check the repair
Pump the brake pedal until firm before moving the vehicle. Check that the wheel rotates without abnormal noise, confirm the ABS harness is secured, and perform a cautious low-speed road check.
Check your vehicle’s repair manual for exact specifications and fit.
