A persistent knocking or clunking noise from the front of a Chevrolet Cavalier is commonly traced to worn suspension components. The most frequent culprits include:- Worn strut mounts/bearings: The mount allows the strut piston to rotate when steering. When the bearing fails, you may hear a pop or creak during turns, and the strut can knock over bumps.- Loose or broken sway bar end links: These links are small but heavily loaded. A failed link produces a metallic rattle or clunk at low speed over uneven pavement.- Worn lower control arm bushings or ball joints: These cause a dull clunk when braking or driving over dips.For replacement, always verify the exact model year, engine, and VIN before ordering. Common part numbers include 172174 for a strut mount/bearing kit and 341244 for a related suspension component, but confirm with an OEM or aftermarket catalog. Inspect all related hardware and replace nuts/bolts if they are damaged.OBD-II diagnostic trouble codes are usually not triggered by mechanical suspension noise. If the Check Engine Light is on, scan the codes separately; P0300, P0171, P0174, and P0440 are common on Cavaliers, but they are unrelated to clunking sounds.After replacing suspension parts, get a wheel alignment to protect tire life and ensure even handling.
