Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, pry bar.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery terminal if necessary for safety.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels using a lug wrench.

3. Inspect and Replace Components

Check the condition of the struts and shock absorbers:
- If leaking or damaged, replace with OEM or quality aftermarket parts.
Inspect bushings:
- If they show signs of cracking or excessive wear, replace them. Use a pry bar to help remove and install new bushings.
Examine sway bar links:
- If they are loose or damaged, replace them. Remove the bolts with a socket set, then install new links and torque to manufacturer specifications.
Test ball joints and control arms:
- If any play is detected, replace them as needed. Remove the control arm bolts, then install new parts and torque them to specifications.

4. Reassemble and Lower the Vehicle

Reinstall the wheels and torque the lug nuts to the manufacturer's specifications.
Lower the vehicle back to the ground.

5. Final Inspection

Reconnect the battery terminal if it was disconnected.
Check for any loose components before taking the vehicle for a test drive.
