Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely raise the front end using jack stands.

2. Inspect and Replace CV Joints

Sub-steps:
1. Remove the front wheel on the affected side using a socket set.
2. Inspect the CV joint boot for tears or leaks. If damaged, replace the boot and joint.
3. To replace the CV joint, disconnect the axle nut using a socket and breaker bar.
4. Detach the lower control arm and any other components blocking access to the CV axle.
5. Remove the old CV joint and install the new one, applying appropriate grease.
6. Reassemble all components in reverse order, ensuring proper torque specifications are followed (typically around 30-40 ft-lbs for the axle nut).

3. Inspect Suspension Components

Sub-steps:
1. Visually inspect the control arms, bushings, and struts for any signs of wear or damage.
2. If bushings are cracked or worn, replace them with OEM parts.
3. Re-tighten all suspension bolts to the manufacturer’s specifications.
4. Test the suspension by pressing down on the front fender to ensure it rebounds properly.

4. Check Wheel Bearings

Sub-steps:
1. Remove the wheel and inspect the wheel bearing for any signs of wear.
2. If excessive play is detected, replace the wheel bearing assembly.
3. Ensure to torque the wheel hub to the manufacturer's specified torque (usually 100-120 ft-lbs).
