Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, impact wrench, pry bar, flashlight.
Safety Warnings: Ensure the vehicle is on a level surface, and use jack stands to secure it before working underneath.

2. Replace Worn Components

Struts/Shocks:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the suspension components.
3. Unbolt the strut or shock from the top and bottom mounting points using a socket set.
4. Remove the strut or shock from the vehicle.
5. Install the new strut or shock in reverse order, ensuring all bolts are torqued to specification (typically around 40-50 lb-ft for struts).
Control Arm Bushings:
1. Remove the wheel and lower the control arm by unbolting it from the frame.
2. Use a pry bar to remove old bushings from the control arm.
3. Press in the new bushings using a bushing tool or a suitable press.
4. Reattach the control arm to the frame and torque bolts to manufacturer specifications.

3. Reassemble and Test

Replace the wheel and lower the vehicle back to the ground.
Conduct a final inspection to ensure all components are secured.
Test drive the vehicle to confirm the noise has been resolved.
