Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves throughout the process.

2. Inspect and Tighten Suspension Components

Tools Required: Socket set, torque wrench
Check all visible suspension bolts and fasteners for tightness.
- Use the socket set to tighten any loose bolts to manufacturer's specifications.
- Refer to the service manual for the correct torque values for each component.

3. Replace Worn Components

Tools Required: Jack and jack stands, wrench set, replacement parts (shocks, struts, bushings as needed)
If worn components are identified, proceed to replace them:
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheel to gain access to the suspension.
- Unbolt the worn shock absorber or strut from the mounting points.
- Install the new component and torque the bolts to specifications.

4. Reassemble and Lower Vehicle

Reattach the wheel and torque the lug nuts to the specified value.
Carefully lower the vehicle back to the ground.
