Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery if working on electrical components.

2. Raise Vehicle

Use a jack to lift the vehicle and secure it with jack stands on a solid part of the frame.
Remove the wheels to gain access to the suspension components.

3. Inspect and Replace Components

Struts/Shocks:
- Remove the top mounting bolts and lower bolts of the strut/shock.
- Replace with new struts/shocks, ensuring proper torque specifications (typically 30-50 ft-lbs for top mounts and 70-80 ft-lbs for lower bolts).
Sway Bar Links:
- Disconnect the sway bar links by removing the nuts using a socket.
- Replace with new links, ensuring they are securely tightened.
Bushings:
- Remove any worn bushings from the control arms and sway bar.
- Install new bushings, following manufacturer specifications for installation and torque.

4. Reassemble

Reinstall the wheels and lower the vehicle back to the ground.
Tighten lug nuts to the manufacturer’s specified torque (typically 75-85 ft-lbs).

5. Final Checks

Reconnect the battery (if disconnected).
Perform a visual inspection to ensure all components are secure and correctly installed.
