Solution

1. Preparation

Gather tools: socket set, torque wrench, jack stands, and safety glasses.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components (if necessary).

2. Inspect and Replace Suspension Components

Raise the Vehicle
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the front or rear wheel if necessary for better access.
Check Shock Absorbers
- Inspect for any oil leakage or physical damage.
- If damaged, remove the old shock absorber:
  - Use a socket to unbolt the upper and lower mounting bolts.
  - Replace with a new shock absorber and torque bolts to manufacturer specifications (typically 25-30 ft-lbs).
Inspect Sway Bar Links
- Check the sway bar links for play or broken bushings.
- If damaged, remove the links by unbolting the nuts at both ends.
- Install the new sway bar links, ensuring they are tightened to the specified torque (usually around 15-20 ft-lbs).
Check Bushings
- Inspect all bushings for wear or deterioration, including control arm bushings.
- Replace any worn bushings by removing the components they are attached to, using a bushing removal tool if necessary.
Tighten Loose Bolts
- Go through all suspension-related bolts and nuts to ensure they are tightened to the manufacturer’s torque specifications.

3. Reassemble and Lower Vehicle

Reattach the wheel, if removed.
Lower the vehicle off the jack stands carefully.
Reconnect the battery if it was disconnected.
