Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the vehicle to cool down if it was recently driven.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle depending on where the noise is most pronounced.
Secure with jack stands for safety.

3. Inspect Suspension Components

Shocks/Struts: Check for leaking fluid or physical damage. If damaged, remove the strut assembly by:
- Detaching the top strut mount bolts using a socket set.
- Releasing the lower strut bolts from the knuckle.
- Remove the strut assembly.
Control Arms and Bushings: Inspect for wear or cracks. If bushings are worn, replace them by:
- Removing the control arm bolts.
- Pressing out old bushings and pressing in new ones.
Sway Bar Links: Inspect sway bar links for looseness. Replace if necessary by:
- Removing the bolts at both ends of the sway bar link.

4. Reassemble Components

After replacing or repairing any faulty parts, reassemble the suspension components in reverse order.
Ensure all bolts are tightened to the manufacturer’s specified torque settings.

5. Lower the Vehicle

Carefully remove jack stands and lower the vehicle back to the ground.
Recheck all fasteners for tightness after the vehicle is back on the ground.
