What Causes Abnormal Noises from the Car Chassis?
2 Answers
Abnormal noises from the car chassis can be caused by the following reasons: Interference Between Components: Due to impacts or the installation of additional equipment, two components may interfere with each other. Solution: Only reshaping, repairing, or replacing the relevant components can eliminate the interference. Loose Bolts or Nuts: Long-term driving on poor road conditions can naturally loosen bolts; improper disassembly or installation can damage bolts; insufficient tightening torque or incorrect bolt specifications. Solution: Tighten or replace the bolts and nuts. Failure of the Driveshaft Universal Joint: Caused by a broken dust cover or oil leakage that was not repaired in time. Solution: Replace the driveshaft universal joint with a new one.
As an experienced mechanic with years of experience, I can tell you that chassis noises are quite common. Worn-out suspension components like ball joints or shock absorber bushings cause squeaking on bumpy roads; leaking or failed shock absorbers produce a dull thud when going over potholes; excessive play in tie rods leads to a clicking sound during turns; rusted or stuck brake calipers or guide pin issues result in sharp friction noises during braking; loose exhaust system hangers also create a humming sound. I recommend immediately lifting the chassis to check for loose parts—don’t wait for minor issues to worsen and compromise driving stability and safety. During regular maintenance, have your technician inspect these areas.
