Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the front or rear wheels (depending on where the noise is localized) using a socket set.

3. Inspect and Replace Suspension Components

A. Struts/Shocks

Inspect: Check the struts or shocks for leaks and physical damage.
Replace if necessary:
1. Remove the mounting bolts at the top and bottom of the strut/shock.
2. Install the new strut/shock in reverse order, ensuring to torque the bolts to manufacturer specifications (typically around 40-50 ft-lbs).

B. Sway Bar Links and Bushings

Inspect: Look for wear or looseness in the sway bar links and bushings.
Replace if necessary:
1. Remove the nuts securing the sway bar links to the sway bar and control arm.
2. Install new sway bar links and torque the nuts to manufacturer specifications (typically around 30 ft-lbs).

4. Reassemble and Lower Vehicle

Reinstall the wheels and lower the vehicle back to the ground.
Tighten the lug nuts to the manufacturer's specifications (typically around 76 ft-lbs).
