🔧 Wheel Bearing - Replacement

Assumption: This procedure covers the front hub/wheel bearing assembly on your Silverado. On this truck, the front bearing is serviced as a hub assembly; if you need the rear bearing, the procedure is different.

When the bearing starts humming, grinding, or develops play, the hub assembly needs to be replaced as a unit. This is a safety-critical repair because a loose or noisy bearing can affect braking, steering, and wheel retention.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

⚠️ Safety & Precautions

• Support the truck securely on jack stands before removing the wheel.
• Do not rely on the jack alone.
• If equipped with ABS, keep the wheel speed sensor wiring clean and undamaged.
• The hub can be stuck tightly in the knuckle. Do not strike the wheel studs with a hammer.
• Battery disconnect is not required for this repair.
• Use caution around the brake rotor and caliper. They are heavy and can shift suddenly.

📋 Before You Begin

• Park on level ground.
• Set the parking brake.
• Chock the rear wheels.
• Loosen the wheel lug nuts before lifting the truck.
• If the truck has been driven recently, let the brakes cool.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the wheel and axle nut

• Use a 21mm socket and breaker bar to loosen the wheel lug nuts before lifting.
• Use a 36mm socket to break loose the front axle nut while the truck is still on the ground.
• Do not remove the axle nut yet.

Step 2: Raise and secure the truck

• Lift the front of the truck with a floor jack (rated 3-ton minimum).
• Support it with jack stands (rated for truck weight).
• Remove the wheel with the 21mm socket.

Step 3: Remove the brake caliper and rotor

• Use an 18mm socket to remove the brake caliper bracket bolts.
• Remove the caliper and hang it with a safe support so the brake hose is not stretched.
• Remove the brake rotor by hand. If stuck, use penetrating oil and gentle taps by hand.

Step 4: Disconnect the wheel speed sensor

• Use a trim clip tool and flat screwdriver to free the sensor harness clips.
• Unbolt or release the sensor from the knuckle if needed using the correct small hand tool for the retaining screw.
• Do not pull on the wire.

Step 5: Remove the axle nut and axle shaft

• Remove the axle nut with a 36mm socket.
• Push the axle shaft inward slightly so it is free from the hub splines.
• If stuck, tap the axle end lightly with a soft mallet. Do not damage the threads.

Step 6: Remove the hub/bearing assembly

• Use a 15mm socket to remove the hub mounting bolts from the back of the knuckle.
• Remove the hub assembly from the knuckle.
• If it is seized, use a hub puller or slide hammer (specialty).
• Clean the knuckle bore with a wire brush and penetrating oil.

Step 7: Install the new hub assembly

• Position the new hub assembly into the knuckle.
• Install the hub bolts by hand first using a 15mm socket.
• Torque the hub bolts to 133 Nm (98 ft-lbs).
• Reinstall the axle shaft fully into the hub splines.
• Install a new axle nut with a 36mm socket.
• Torque the axle nut to 320 Nm (236 ft-lbs).

Step 8: Reinstall the brake parts and wheel

• Reinstall the rotor.
• Reinstall the caliper bracket with an 18mm socket.
• Torque the caliper bracket bolts to 190 Nm (140 ft-lbs).
• Reattach the wheel speed sensor and harness clips.
• Install the wheel and snug the lug nuts with a 21mm socket.
• Torque the lug nuts to 190 Nm (140 ft-lbs) in a star pattern.

Step 9: Lower the truck and finish tightening

• Lower the truck carefully off the jack stands.
• Recheck lug nut torque with a torque wrench.

✅ After Repair

• Start the truck and listen for bearing noise.
• Check for ABS warning lights.
• Test brake pedal feel before driving.
• Drive slowly at first and listen for rubbing or humming.
• Recheck lug nut and axle nut torque after a short test drive if needed.
