Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Remove Wheel and Brake Assembly

Tools Required: Jack, jack stands, lug wrench, socket set
Remove the lug nuts using the lug wrench and take off the wheel.
Remove the brake caliper by unbolting it from the bracket; secure it away from the rotor (do not let it hang by the brake line).
Remove the brake rotor by taking out the retaining screws or bolts.

3. Remove Wheel Bearing

Inspect the dust cap and remove it if present.
Remove the retaining ring (if applicable) using snap ring pliers.
Use a socket or bearing puller to carefully extract the wheel bearing from the hub.
Clean the hub area thoroughly to prepare for the new bearing.

4. Install New Wheel Bearing

Lubricate the new wheel bearing with the appropriate grease.
Insert the new bearing into the hub, ensuring it is seated properly.
Reinstall any retaining rings or clips that were removed.
Replace the dust cap if applicable.

5. Reassemble Brake Assembly and Wheel

Reinstall the brake rotor and caliper, tightening bolts to manufacturer specifications (typically around 25-30 lb-ft for caliper bolts).
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts to the specified torque (usually around 80-100 lb-ft).

6. Final Checks

Reconnect the negative battery terminal.
Test the wheel by spinning it to ensure there are no unusual noises or resistance.
