Solution

1. Preparation

Tools Required: Socket set, wrench set, jack stands, and a pry bar.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to avoid accidental airbag deployment.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is coming from.
Place jack stands securely under the vehicle for safety.

3. Inspect and Replace Components

A. Shock Absorbers/Struts

Sub-steps:
1. Locate the upper and lower mounting bolts of the shock absorber/strut.
2. Remove the bolts using a socket set.
3. Pull the shock absorber/strut out.
4. Install the new shock absorber/strut by reversing removal steps, ensuring all bolts are tightened to the manufacturer’s torque specifications.

B. Control Arm Bushings

Sub-steps:
1. Use a pry bar to check for play in the control arm bushings.
2. If worn, remove the control arm from the vehicle.
3. Press out the old bushings and press in the new ones.
4. Reinstall the control arm and torque bolts to specifications.

C. Other Loose Components

Sub-steps:
1. Tighten any loose bolts found during the initial inspection.
2. Replace any damaged components as necessary.
