Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, bearing puller, wheel bearing grease, clean rags.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts using the lug wrench.
Lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Components

Remove the brake caliper by unscrewing the caliper mounting bolts. Support the caliper with a bungee cord or rope to avoid stressing the brake line.
Remove the brake rotor (if applicable) by unscrewing any retaining screws or gently pulling it off the hub.

4. Remove Hub Assembly

Remove the dust cap covering the hub assembly (if applicable).
Unscrew the axle nut using a socket wrench, and remove the hub assembly from the spindle.
Use a bearing puller to extract the old wheel bearings from the hub assembly.

5. Install New Bearings

Clean the hub assembly thoroughly with a rag.
Apply a thin layer of wheel bearing grease to the new bearings and the hub.
Install the new bearings into the hub assembly using a bearing installer or press.
Reattach the hub assembly to the spindle and secure it with the axle nut, tightening to the manufacturer’s specified torque.

6. Reassemble Brake Components and Wheel

Reinstall the brake rotor and caliper, ensuring all bolts are tightened to specifications.
Place the wheel back onto the hub, hand-tighten the lug nuts, and lower the vehicle.
Torque the lug nuts to the manufacturer’s specifications.
