Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Use wheel chocks to prevent the vehicle from rolling.

Tools Required:

Jack and jack stands
Socket set
Torque wrench
Pry bar
Screwdriver

2. Inspect and Replace CV Joints

Lift the Vehicle: Use the jack to raise the front of the vehicle and secure it with jack stands.
Remove the Wheel: Take off the wheel to access the CV joint.
Inspect the CV Joint: Check for any signs of wear, such as torn boots or excessive play in the joint.
Replace if Necessary: If the CV joint is damaged:
- Remove the CV axle from the transmission.
- Install the new CV axle in reverse order of removal.
- Torque the axle nut to the manufacturer's specifications.

3. Replace Sway Bar Links and Bushings

Locate the Sway Bar: Identify the sway bar and its links attached to the lower control arm and the chassis.
Remove the Old Links: Use a socket wrench to remove the bolts securing the sway bar links.
Install New Links: Position the new sway bar links and secure them with the bolts. Ensure they are torqued to specifications.
Inspect Bushings: If bushings are worn, remove the sway bar and replace the bushings, then reinstall the sway bar.

4. Check and Replace Wheel Bearings (if necessary)

Remove the Brake Caliper: Unbolt the caliper from the rotor and secure it, do not let it hang by the brake line.
Remove the Rotor: Take off the rotor to access the wheel bearing.
Inspect the Bearing: Check for play or roughness in the bearing.
Replace if Needed: If damaged, remove the old bearing and install a new one, ensuring proper lubrication.
