Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Raise the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Wheel Bearings

Sub-steps:
1. Remove the front wheels using a lug wrench.
2. Inspect the wheel bearings for any signs of grinding or roughness.
3. If bearings are worn, remove the hub assembly by unbolting it from the knuckle.
4. Replace the wheel bearings with new ones, ensuring proper alignment.
5. Reassemble the hub assembly and torque bolts to manufacturer specifications.

3. Examine and Replace CV Joints

Sub-steps:
1. Locate the CV axle and inspect the boots for cracks or grease leakage.
2. If damaged, remove the CV axle from the transaxle and wheel hub.
3. Install a new CV joint or axle as needed, ensuring it is properly seated.
4. Reattach the axle nut and torque to manufacturer specifications.

4. Inspect Brake Components

Sub-steps:
1. Check brake pads and calipers for proper installation and alignment.
2. Replace any worn or damaged brake pads and ensure calipers are securely mounted.
3. Reinstall the wheel and torque the lug nuts to specifications.

5. Check Suspension Components

Sub-steps:
1. Inspect control arms, bushings, and struts for wear and damage.
2. Replace any worn components as necessary.
3. Ensure all fasteners are tightened to the appropriate torque values.
