Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Replace Suspension Components

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a socket set.
3. Inspect the control arm bushings for cracks or excessive wear; replace if necessary.
4. Check the ball joints for play; replace if any movement is detected.
5. If the CV joints are damaged, remove the axle nut and the axle from the hub; replace it with a new CV axle.

3. Lubricate and Reassemble

Sub-steps:
1. Lubricate any new bushings or joints as required by the manufacturer.
2. Reinstall the control arms and ball joints, tightening bolts to the manufacturer-specified torque values (usually around 50-70 ft-lbs, but check the service manual).
3. Reattach the CV axle if replaced and torque the axle nut to 150 ft-lbs.
4. Reinstall the wheels and lower the vehicle back to the ground.
