Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before working underneath.

3. Inspect and Replace Components

Suspension Components:
- Remove the wheel to access the suspension.
- Check the control arms, bushings, and sway bar links for wear.
- Replace any worn components with new parts, ensuring to torque bolts to manufacturer specifications.
Shock Absorbers/Struts:
- If shocks/struts are found to be leaking or not functioning properly, remove them by unbolting from the top mount and lower mount.
- Install new shocks/struts, ensuring they are properly seated and secured with correct torque.

4. Reassemble and Lower Vehicle

Reinstall the wheels and lower the vehicle back to the ground.
Reconnect the battery and ensure all tools are removed from the work area.
