Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Inspect and Replace Wheel Bearings

Raise the Vehicle: Use a jack to lift the front end and secure it with jack stands.
Remove Front Wheel: Use a socket set to remove the wheel lug nuts and take off the wheel.
Check Wheel Bearings: Spin the hub and listen for grinding noise. If present, proceed to replace.
Remove the Brake Caliper:
- Use a ratchet and socket to unbolt the caliper from the bracket.
- Hang the caliper with a wire to avoid straining the brake line.
Remove the Brake Rotor: Unbolt and remove the rotor to access the wheel bearing.
Remove the Hub Assembly:
- Unbolt the hub assembly from the knuckle using a socket set.
- Use a puller if necessary to extract the hub.
Install New Bearing: Press the new bearing into the hub assembly using a bearing press.
Reassemble Components:
- Reinstall the hub assembly, rotor, and brake caliper.
- Torque all bolts to manufacturer specifications (typically around 70-80 ft-lbs for the caliper).
Reinstall Wheel: Place the wheel back on, hand-tighten the lug nuts, and lower the vehicle.

3. Inspect CV Joints

Check for Damage: While the vehicle is lifted, inspect the CV boots for cracks and signs of grease leakage.
Replace if Necessary: If damaged, replace the entire CV axle by unbolting it from the transmission and hub assembly.
