Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, stethoscope (for noise diagnosis).
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported before working underneath.

2. Remove Wheel

Loosen the lug nuts of the front or rear wheel (depending on the noise location) with a socket wrench.
Raise the vehicle using a jack and support it with jack stands.
Remove the wheel to access suspension components.

3. Inspect and Replace Components

Suspension Bushings:
- Use a pry bar to check for play in the bushings.
- If damaged, remove the old bushings using a bushing removal tool.
- Install new bushings, ensuring they are properly aligned and seated.
Ball Joints:
- Inspect for wear; if movement is excessive, replace the ball joint.
- Remove the retaining nut and use a ball joint separator to detach it from the control arm.
- Install the new ball joint and torque to manufacturer specifications.
Struts/Shocks:
- If struts are leaking or damaged, remove the retaining bolts and disconnect the strut from the knuckle.
- Replace with new struts/shocks, ensuring proper alignment and torque settings.

4. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value.
Conduct a test drive to verify that the noise has been resolved.
