Diagnostic Steps

1
Inspect Suspension Components: Visually check all suspension parts, including struts, shocks, control arms, and bushings for signs of wear or damage.
2
Check for Loose Hardware: Ensure all bolts and nuts on suspension components are properly tightened, especially around the control arms and strut mounts.
3
Listen While Moving: Drive the vehicle over various road surfaces (smooth, gravel, potholes) to identify the specific conditions that trigger the noise.
4
Perform Bounce Test: Push down on each corner of the vehicle and observe for excessive bouncing, which may indicate worn shocks or struts.
5
Inspect Wheel Bearings: Raise the vehicle and check for play in the wheel bearings by shaking the wheel side to side and up and down.
6
Check for Fluid Leaks: Examine struts and shocks for any signs of fluid leakage, which can indicate failure.
