Solution

1. Preparation

Park the vehicle on a flat surface and engage the parking brake.
Gather tools and safety gear: jack stands, socket set, torque wrench, pry bar, and safety glasses.

2. Raise the Vehicle

Use a floor jack to lift the front or rear (depending on where the noise is coming from) of the vehicle.
Secure the vehicle with jack stands under the frame.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel for easier access to the suspension components.

4. Replace Worn Components

A. Sway Bar Links

Remove: Use a socket to remove the bolts securing the sway bar links.
Install: Replace with new sway bar links and tighten to manufacturer specifications (typically around 40-50 ft-lbs).

B. Control Arm Bushings

Remove: Use a pry bar to detach the control arm from the vehicle and remove the old bushings.
Install: Press in new bushings and reattach the control arm, tightening bolts to the specified torque (usually around 70-80 ft-lbs).

C. Struts (if applicable)

Remove: Detach the strut assembly by removing the top and bottom bolts.
Install: Replace with new struts, ensuring to torque all fasteners to the recommended specifications (typically 60-70 ft-lbs for the bottom bolts).

5. Reassemble Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to manufacturer specifications (usually around 80-100 ft-lbs).

6. Road Test

Take the vehicle for a test drive to ensure the knocking noise has been resolved.
