Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, stable surface and ensure it is in gear or in "Park."
Disconnect the battery to ensure safety during repairs.

2. Inspect Suspension Components

Tools Required: Socket set, torque wrench, pry bar
Remove the wheel on the side where the noise is observed using a socket set.
Inspect the struts/shocks for leaks, dents, or signs of wear.
Check control arms and bushings for any signs of cracking or excessive wear.
Tighten any loose bolts to manufacturer specifications using a torque wrench.

3. Replace Worn Components

Tools Required: Socket set, torque wrench, new suspension components
If any components (such as control arms, bushings, or struts) are found to be damaged or worn, remove the affected component.
Follow the manufacturer’s guidelines for installation, ensuring proper orientation and alignment.
Torque all fasteners to the specifications stated in the service manual.

4. Reassemble and Test

Reinstall the wheel and lower the vehicle back to the ground.
Reconnect the battery.
Perform a bounce test again to ensure the suspension is functioning properly.
