Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Torque wrench
- Socket set
- Screwdriver set
- Brake cleaner
Safety Warnings: Ensure the vehicle is on a flat surface, use wheel chocks, and wear safety glasses.

2. Remove Wheel

Loosen the lug nuts slightly (do not remove).
Use the jack to lift the vehicle and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Wheel Bearing

Inspect the Hub Assembly: Look for signs of rust, wear, or damage.
Remove the brake caliper and rotor if necessary, following these sub-steps:
- Use a socket set to remove the caliper bolts.
- Hang the caliper using a wire or bungee to avoid stressing the brake line.
- Remove the rotor by pulling it off the hub.
Remove the wheel bearing retaining nut (if applicable) using a socket and ratchet.
Use a bearing puller to remove the old bearing from the hub assembly.
Clean the hub assembly with brake cleaner.
Install New Wheel Bearing:
- Place the new bearing into the hub.
- Use a bearing press or socket to ensure it is seated correctly.
- Reinstall the retaining nut and tighten to the manufacturer's specifications (usually specified in the service manual).
Replace the rotor and caliper, ensuring all bolts are torqued to the proper specifications.

4. Reinstall Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts, then lower the vehicle back to the ground.
Use a torque wrench to tighten the lug nuts to the manufacturer's specifications in a criss-cross pattern.
