Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Use wheel chocks to prevent movement and jack stands for safety.

2. Inspect and Replace Suspension Components

Sub-steps:
- Raise the vehicle using a hydraulic jack and secure it with jack stands.
- Remove the front wheels using a socket set.
- Visually inspect control arms, bushings, and tie rods for wear (cracks, tears, or excessive play).
- If any components are damaged, proceed to replace them by removing the fasteners using a torque wrench.
- Install new parts and torque them to manufacturer specifications.

3. Check and Replace CV Joints

Sub-steps:
- Disconnect the outer CV joint from the wheel hub by removing the retaining nut.
- Pull the CV axle out of the transmission or differential.
- Inspect the CV joint for damage or excessive play; replace if necessary.
- Reinstall the CV joint, ensuring to apply the correct torque to the retaining nut.

4. Inspect and Replace Wheel Bearings

Sub-steps:
- Remove the brake caliper and rotor to access the wheel bearing.
- Use a bearing puller to remove the old bearing from the hub assembly.
- Clean the housing and install a new wheel bearing, ensuring it is seated correctly.
- Reassemble the brake components and wheel, torqueing to specifications.
