Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Inspect Suspension Components

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the suspension components.
3. Visually inspect the control arms, bushings, struts, and springs for any signs of damage or wear.
4. Replace any worn-out bushings or components as necessary.

3. Examine Shock Absorbers

Sub-steps:
1. With the wheel still removed, check the shock absorbers for fluid leaks or physical damage.
2. Push down on the vehicle at each corner to see if it rebounds excessively.
3. Replace any defective shock absorbers with OEM or high-quality aftermarket parts.

4. Check Wheel Bearings

Sub-steps:
1. Rotate the wheel by hand to feel for any roughness or grinding.
2. If noise is detected, remove the hub assembly and replace the wheel bearings if needed.

5. Reassemble and Lower the Vehicle

Sub-steps:
1. Reinstall the wheel and torque the lug nuts to the manufacturer specifications (typically around 80-100 ft-lbs).
2. Lower the vehicle to the ground and reconnect the battery.
