Wheel Bearing Hub - Front

This procedure covers the removal and replacement of the front wheel bearing hub assembly on a 2014-2018 Chevrolet Silverado 1500 with the 5.3L V8 engine.

Warnings

Tools required

Parts

• Front wheel bearing hub assembly × 1 — Use OEM specification or quality aftermarket (AC Delco FW367)
• Thread locker compound × 1 — Medium strength (Loctite 243 or equivalent)

Preparation

1. Park vehicle on level surface and engage parking brake
2. Loosen front wheel lug nuts 1-2 turns while vehicle is on ground
3. Raise front of vehicle and support securely on frame-mounted jack stands
4. Remove front wheel completely
5. Apply penetrating oil to hub bolts accessible from behind the steering knuckle and allow to soak for 10-15 minutes if vehicle has high mileage or is from rust-prone area

Procedure

1. 1

   Remove brake caliper bracket assembly
   Remove the two 18mm caliper bracket bolts from the rear of the steering knuckle. Remove the entire caliper and bracket assembly as one unit. Support the caliper assembly with wire or zip ties hung from the upper control arm or frame to prevent stress on the brake hose. Do not let caliper hang by the brake line.
2. 2

   Remove brake rotor
   Slide the brake rotor off the hub studs. If rotor is stuck due to corrosion, tap around the hat section (center) with a hammer to break it loose. Some rotors have threaded holes for puller bolts if severely stuck.
3. 3

   Disconnect ABS wheel speed sensor
   Locate the ABS wheel speed sensor connector behind the steering knuckle or in the wheel well area. Press the connector release tab and carefully disconnect the sensor. Remove the 10mm bolt securing the ABS sensor wire bracket to the knuckle if present. Do not pull on the sensor wire itself.
   ⚠ABS sensor wiring is fragile. Handle connector carefully and avoid bending or twisting the wire to prevent sensor damage.

4. 4

   Access hub mounting bolts
   Turn the steering wheel to full lock (away from the side being serviced) to gain better access to the hub bolts. The three hub mounting bolts are accessed from behind the steering knuckle. You may need to reach around or through openings in the knuckle.
5. 5

   Remove hub assembly mounting bolts
   Using a 13mm socket, remove the three hub mounting bolts from the rear of the steering knuckle. These bolts pass through from the back and thread into the hub assembly. Keep track of bolt locations as they may be different lengths. Support the hub assembly as you remove the final bolt.
   ⚠Hub assembly will become loose once final bolt is removed. Support the hub to prevent it from falling.

6. 6

   Remove hub assembly from knuckle
   Pull the hub assembly straight out from the front of the steering knuckle. If stuck, gently tap the wheel studs with a soft-faced hammer or use a pry bar between the hub flange and knuckle face. The ABS sensor ring is typically integrated into the hub and will come out with the assembly.
7. 7

   Clean mounting surfaces
   Use a wire brush to thoroughly clean the hub mounting face on the steering knuckle, removing all rust, dirt, and corrosion. Clean the bolt holes with a wire brush or thread chaser. Ensure the mounting surface is flat and free of debris for proper hub seating.
8. 8

   Install new hub assembly
   Apply a thin coat of anti-seize compound to the knuckle mounting surface (avoid getting any on bolt holes). Align the new hub assembly with the knuckle bore and slide it into position, ensuring the ABS sensor ring faces outward and the mounting holes align. Push firmly to fully seat the hub flange against the knuckle face.
9. 9

   Install and torque hub bolts
   Apply medium-strength thread locker to the threads of the three hub mounting bolts. Insert bolts from the rear of the knuckle and hand-thread them into the hub assembly. Tighten bolts in a star pattern to ensure even seating. Torque all three bolts to specification using a torque wrench.

10. 10

    Reconnect ABS sensor
    Reconnect the ABS wheel speed sensor connector, ensuring it clicks securely into place. If equipped, reinstall the sensor wire bracket bolt to the knuckle and torque to specification. Ensure wiring is properly routed away from moving components and heat sources.

11. 11

    Reinstall brake rotor
    Slide the brake rotor onto the hub studs. Ensure the rotor sits flush against the hub face. If installing a new rotor, clean off any protective coating with brake cleaner.
12. 12

    Reinstall brake caliper bracket assembly
    Remove caliper support wire. Position the caliper bracket assembly over the rotor and align bolt holes with the steering knuckle. Apply fresh medium-strength thread locker to the caliper bracket bolt threads. Install both bolts and torque to specification in a cross pattern.
13. 13

    Reinstall wheel and lower vehicle
    Install the wheel onto the hub studs. Hand-thread all lug nuts to prevent cross-threading. Snug lug nuts in a star pattern with a wrench. Lower vehicle until tire just contacts ground but weight is still on jack stands. Torque lug nuts to specification in a star pattern. Fully lower vehicle and remove jack stands.

Reassembly

1. Torque values are critical for proper hub bearing function and brake performance. Verify all fasteners are torqued correctly.
2. Thread locker is recommended on hub bolts and required on caliper bracket bolts to prevent loosening from vibration and thermal cycling.

Verification

• With vehicle on ground, attempt to rock the tire top-to-bottom to check for play. There should be no perceptible movement.
• Start vehicle and verify ABS warning light extinguishes after initial bulb check (within 3-5 seconds).
• Perform a test drive at low speed (under 10 mph) in a safe area. Apply brakes gently to verify proper braking without pulsation or noise.
• Drive vehicle and verify no abnormal noise, vibration, or ABS warning light. Recheck wheel lug nut torque after 50-100 miles of driving.
