Q: How to Service and Repair the Wheel Speed Sensor on a Buick Enclave?
A: Inspection of metal particles on the Wheel Bearing encoder surface must occur before preparing to replace the front sensor. Issue cleaning if necessary to maintain sensor signal clarity. Take off the air cleaner component before changing the right front Wheel Speed Sensor and unplug its electrical connection. Lift the car and take away the tire and wheel unit. Unclip the Wheel Speed Sensor wire grommet from the wheelhouse opening then gently draw out the sensor wire and connector. Detach the wheelhouse routing clip holding the wire harness first before taking off clip and . Clean the mounting surface of the Steering Knuckle then remove the Wheel Speed Sensor bolt to extract the sensor directly upwards from its location. Put the new Wheel Speed Sensor into the Steering Knuckle space and fix it using the Wheel Speed Sensor bolt with a torque setting of 9 n.m (80 lb in). Attach the suspension clips and to their original location on the strut before inserting the wire electrical connector through the wheelhouse and placing the wire harness grommet into its housing. Join the Wheel Speed Sensor electrical connector and put back on the tire-and-wheel unit before placing in the air cleaner component if needed. Complete your diagnostic procedure by running the vehicle system test to make sure everything works as planned.
Q: How to replace the front wheel speed sensor without F45 on Buick LaCrosse?
A: The initial steps to replace a front Wheel Speed Sensor are to lift up the vehicle and secure it properly. Take off the tire and wheel combination now. Detach the Wheel Speed Sensor connector pin from the frame and free it. Lower the clip from the frame while also removing the secondary clip at the end of the Control Arm. Spotlessly clean the area around the Wheel Speed Sensor before removing the Wheel Speed Sensor bolt and pulling the sensor out of its position in the Steering Knuckle. Loosen the harness clip locking the Wheel Speed Sensor to the Steering Knuckle and disconnect the part. When installing put the Wheel Speed Sensor onto the Steering Knuckle and push the harness clip onto its receptacle. Secure the Wheel Speed Sensor bolt by turning it to 9 nm using a torque meter. Link the Wheel Speed Sensor electrical connector to frame parts and secure it to the structure afterward add both harness clips to frame pieces and lower control arms. Reinstall the wheel and tire components as they were before.
Q: How to Properly Replace a Wheel Speed Sensor on Buick Rainier?
A: Raise the vehicle and take off the wheel and tire to get to the brake rotor for Wheel Speed Sensor replacement. Pull off the Wheel Speed Sensor wiring harness retainers and disconnect the electric connection. Use fingers to gently draw the sensor straight from the bore space without tools to avoid breaking the sensor casing. Maintaining the stainless steel shim directly attached to the bearing assembly will help preserve sensor and abs performance so do not attempt to remove it. Keep the bearing lubricant protected during cleaning and hub work to prevent fast bearing breakdown. Install the new speed sensor and its included o-ring into the hub and bearing assembly. Dispose of the old o-ring and apply light bearing grease to only the o-ring and the sensor ends that touch it. Avoid placing grease inside the sensor bore. Put the speed sensor into the hub and bearing parts then fasten the speed sensor mounting screw at 17 nm (12 ft. Lbs.). Plug back the electrical wires while changing to new retaining clips from the kit. Place both parts of the Wheel Speed Sensor wiring harness onto its designated locations on the frame and control arm. Then put on the brake rotor before putting back the wheel and tire.
