Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts during the repair.

2. Inspect and Replace CV Joints

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels to gain access to the CV joints.
3. Inspect the outer and inner CV boots for cracks or tears. If damaged, replace the CV joint.
4. Remove the retaining clip from the CV joint if necessary.
5. Clean the area and apply fresh grease before installing the new CV joint.
6. Reinstall the wheel and lower the vehicle.

3. Check and Secure Heat Shields

Sub-steps:
1. Visually inspect the heat shields around the exhaust for any signs of loosening or damage.
2. Tighten any loose bolts or clamps securing the heat shield.
3. If damaged, replace the heat shield as necessary.

4. Inspect and Replace Wheel Bearings

Sub-steps:
1. Remove the wheel hub assembly to gain access to the wheel bearings.
2. Check for play in the bearings by hand-spinning them and listening for noise.
3. If play or noise is detected, press out the old bearings and press in new ones.
4. Reassemble the wheel hub and ensure proper torque specifications are followed.
