Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: Socket set, jack and jack stands, torque wrench, and suspension tool kit.

2. Replace Worn Shocks/Struts

Sub-steps:
1. Lift the Vehicle: Use a jack to lift the vehicle and secure it with jack stands.
2. Remove Wheel: Take off the wheel to access the suspension components.
3. Disconnect Shock/Strut: Remove the mounting bolts from the top and bottom of the shock or strut using a socket set.
4. Install New Shock/Strut: Position the new shock or strut in place and secure it with mounting bolts. Torque bolts to manufacturer specifications (typically around 40-60 ft-lbs but refer to service manual).
5. Reattach Wheel: Place the wheel back on and tighten lug nuts to the appropriate torque (usually around 80-100 ft-lbs).
6. Lower the Vehicle: Carefully lower the vehicle back to the ground.

3. Inspect and Replace Springs (if necessary)

Sub-steps:
1. Remove Shock/Strut Assembly: If springs are found to be damaged, remove the shock/strut assembly from the vehicle.
2. Use Spring Compressor: Utilize a spring compressor to safely compress the spring before removal.
3. Replace Spring: Remove the old spring and install the new one, ensuring it is seated correctly.
4. Reassemble Shock/Strut: Reassemble the shock/strut assembly and reinstall it in the vehicle.
