⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely raised and supported before working underneath it.
•Disconnect the battery before working on electrical components, if applicable.

Symptoms

•Popping noise when driving over bumps or uneven surfaces
•Possible creaking or rattling noises in the suspension
•Vibration felt in the cabin over rough terrain
•Decreased ride comfort and stability

Diagnostic Steps

1
Perform a visual inspection of the suspension components, including struts, control arms, and bushings, for signs of wear or damage.
2
Check the tightness of all suspension-related bolts and nuts using a torque wrench.
3
Test the suspension by pushing down on each corner of the vehicle to observe if it rebounds smoothly without excessive noise.
4
Inspect wheel wells for any loose or damaged plastic liners or other components that could be causing noise.
5
Use a stethoscope or mechanic's stethoscope to pinpoint the source of the noise while having someone else bounce the suspension.
