Solution

1. Preparation

Tools: Jack, jack stands, socket set, torque wrench, pry bar.
Lift the vehicle using a jack and secure it with jack stands.
Remove the front wheels for better access to suspension components.

2. Inspect and Replace Suspension Components

Check Control Arms:
- Use a pry bar to test for play in control arm bushings.
- If damaged, remove the control arm by loosening and removing the bolts.
- Replace with new control arms and torque to manufacturer specifications.
Inspect CV Joints:
- Check for torn boots or leaking grease.
- If the CV joint is damaged, remove the axle nut and disconnect the axle from the hub.
- Replace the CV joint or axle as necessary, ensuring proper lubrication.
Examine Strut Mounts:
- Inspect the strut mounts for cracks or wear.
- If damaged, remove the strut assembly by unbolting the strut from the lower control arm and the top mount.
- Replace the strut mount and reassemble, torquing bolts to specifications.

3. Reassemble

Reinstall the front wheels and lower the vehicle.
Torque the wheel lug nuts to the specified value.
