1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the vehicle to cool down if it has been in operation.

2. Inspect Suspension Components

Sub-steps:
- Raise the vehicle using a hydraulic jack and secure it on jack stands.
- Visually inspect the shocks/struts for any fluid leaks or physical damage.
- Examine the control arms and bushings for cracking or deterioration.

3. Tighten Suspension Bolts

Sub-steps:
- Using a torque wrench, check and tighten all suspension-related bolts to the manufacturer's specifications.
- Focus on the strut mounts, control arm bolts, and sway bar link connections.

4. Replace Worn Sway Bar Links or Bushings

Sub-steps:
- If worn, remove the sway bar links using a socket set.
- Install new sway bar links or bushings, ensuring they are properly torqued.
- Reattach any components removed for access.

5. Reassembly and Lower Vehicle

Sub-steps:
- Remove jack stands and lower the vehicle back to the ground.
- Ensure all tools are accounted for and that the workspace is clean.
