Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Brake Inspection and Replacement

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect brake pads for thickness; replace if less than 3 mm.
3. Check rotors for grooves or warping; machine or replace as necessary.
4. Clean the brake caliper and ensure proper lubrication on caliper slides.
5. Reassemble the brake components and wheel; torque lug nuts to manufacturer specification (typically 90-120 Nm).

3. Wheel Bearing Inspection and Replacement

Sub-steps:
1. Lift the vehicle securely with a jack and support it with jack stands.
2. Grasp the wheel at 12 and 6 o'clock positions to check for play; if present, replace the bearing.
3. Remove the brake caliper and rotor to access the wheel hub.
4. Use a bearing puller to remove the old bearing; replace with a new bearing.
5. Reassemble the components and ensure everything is torqued to specification.

4. Driveshaft and CV Joint Inspection

Sub-steps:
1. Inspect the driveshaft for any visible damage or leaks in the CV boots.
2. If damage is noted, remove the driveshaft using the appropriate socket and wrench.
3. Replace any worn CV joints or the complete driveshaft as necessary.
4. Reinstall the driveshaft, ensuring all fasteners are torqued to specification.
