Steps
Remove the wheel and caliper
Remove the center cap and wheel lock, loosen the lug nuts, then raise and support the truck. Remove the wheel and caliper bracket fasteners, suspend the caliper, and take off the rotor.
Remove the backing plate and sensor
Remove the backing plate fasteners to access the sensor. Remove its 5 mm retaining bolt, carefully withdraw the sensor from the hub, unplug the harness, and release its mounting clip.
Install and route the new sensor
Route the replacement harness along the original path and secure it to the spindle. Connect the electrical plug, seat the sensor in the hub, and install its retaining bolt.
Reassemble the backing plate and brakes
Reinstall the backing plate, rotor, and caliper bracket, tightening the bracket bolts to the vehicle's specification. Refit the caliper and confirm the sensor wire cannot rub the rotor or wheel.
Reinstall the wheel and verify ABS
Mount the wheel and start its lug nuts by hand. Lower the truck, torque the nuts to specification in a crossing pattern, reinstall the center cap, and confirm the ABS warning lamp clears.
Check your vehicle’s repair manual for exact specifications and fit.
