Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery.
Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, OBD-II scanner.

2. Inspect and Replace Brake Components (if necessary)

Sub-steps:
1. Remove the wheel by loosening the lug nuts with a lug wrench.
2. Place the jack under the vehicle’s designated lifting points and raise it securely with jack stands.
3. Remove the brake caliper by unscrewing the caliper bolts; hang it with a bungee cord to avoid stressing the brake line.
4. Inspect the brake pads for thickness; if they are less than 3mm, replace them.
5. Check the brake rotors for grooves or warping; if damaged, replace the rotors.
6. Reassemble the brake components, ensuring the caliper is reattached securely.

3. Check Wheel Bearings

Sub-steps:
1. Spin the wheel by hand to listen for noise indicative of bad bearings.
2. If noise is present, remove the wheel hub assembly by unscrewing the retaining bolts.
3. Inspect the bearings for smoothness; if rough, replace them.
4. Reinstall the wheel bearing assembly with proper torque specifications.

4. Inspect Drivetrain Components

Sub-steps:
1. Check the driveshaft and CV joints for any tears in the rubber boot.
2. Replace any damaged CV joints or boots as necessary.
3. Ensure the driveshaft is securely connected and not making contact with any other components.
