Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface, and the ignition is off.
Tools Required: Jack, jack stands, socket set, torque wrench, wheel chocks, and a bearing puller.

2. Remove the Wheel

Loosen the lug nuts slightly before lifting the vehicle.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove the Brake Components

Remove the brake caliper by unscrewing the caliper bolts. Support the caliper with a bungee cord or similar to avoid straining the brake line.
Take off the brake rotor by removing any retaining screws or clips.

4. Remove the Hub Assembly

Remove the dust cap if present.
Take out the cotter pin and nut securing the hub to the spindle using a socket.
Use a bearing puller to extract the hub assembly from the spindle, ensuring to follow the manufacturer's torque specifications when reinstalling.

5. Inspect and Replace Bearings

Inspect the bearings for any signs of wear or damage.
If they are damaged, press out the old bearings using the bearing puller and install new bearings using a bearing press.
Ensure to lubricate the new bearings as per manufacturer specifications.

6. Reassembly

Reattach the hub assembly to the spindle and secure it with the nut and cotter pin.
Reinstall the brake rotor and caliper, ensuring all bolts are torqued to manufacturer specifications.
Replace the wheel and lug nuts, and lower the vehicle back to the ground.
