Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery.

2. Inspecting and Replacing 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 using a socket set.
3. Inspect the CV joints for any signs of damage or excessive play.
4. If damaged, use a socket wrench to remove the CV axle from the hub and the transmission.
5. Replace the CV joint with a new one, ensuring proper alignment.
6. Reinstall the axle and tighten the bolts to manufacturer specifications (typically around 30-50 ft-lb).

3. Inspecting and Replacing Wheel Bearings

Sub-steps:
1. While the vehicle is elevated, grasp the wheel at the 12 and 6 o'clock positions and shake to check for play.
2. If play is detected, remove the brake caliper and rotor using a socket set.
3. Remove the hub assembly to access the wheel bearing.
4. Replace the bearing using a bearing puller and reinstall the new bearing.
5. Reassemble the hub and brake components, ensuring all fasteners are torqued appropriately.

4. Checking Suspension Components

Sub-steps:
1. Inspect control arms, bushings, and struts for signs of wear or damage.
2. Replace any worn bushings or struts using a socket set and torque to specifications.
3. Reassemble all components and ensure they are secured properly.
