DIY Chassis Noise Diagnosis: Identify Faults by Sound
By Sound
- Clunk (metal, bumps/turns): sway links, ball joints, arm bushings
- Creak (rubber, slow bumps): mounts, bushings aged
- Hum (speed-related): wheel bearing (louder side in turns = faulty)
- Metal knock (deep holes): topping strut, loose parts, broken spring
- Rattle in wheel (turning): steering gear/column/clock spring
By Scenario
- Turning in place: strut bearing, gear
- Straight over bump: strut, spring, mount
- One-side bump: sway link, that arm
- Braking: brake system
- Reversing full lock: CV joint, strut bearing
DIY Steps
- Note: road, action, sound
- Bounce test at towers
- Visual: boots, joints, leaks
- Pry joints for play
Huami tip: diagnose first so you are not over-sold repairs.
