Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel using a jack and jack stands.
2. Inspect the brake pads; if worn below the recommended thickness (usually 3mm), replace them.
3. Check the rotors for scoring or warping; replace if necessary.
4. Reassemble the brakes, ensuring all components are secured and torqued to manufacturer specifications.

3. Check Wheel Bearings

Sub-steps:
1. While the wheel is off, check for movement by shaking the wheel top and bottom; if there’s excessive play, the bearing needs replacement.
2. Remove the wheel hub assembly according to the service manual.
3. Replace the wheel bearing using a bearing puller and install a new one.
4. Reassemble the wheel hub, ensuring all bolts are tightened to the correct torque.

4. Inspect Drivetrain Components

Sub-steps:
1. Examine the CV joints for cracks or tears in the rubber boots.
2. If damaged, replace the CV joint or axle.
3. Check the driveshaft for any signs of play or damage.
4. Reassemble and torque all components to specified values.
