What Causes the Abnormal Noise When a Corolla is Driving at Low Speed?
2 Answers
Corolla low-speed driving abnormal noise causes are as follows: Body noise: This issue is usually due to insufficient body rigidity, causing the vehicle to deform during driving, resulting in friction or shaking between the doors and the frame, or friction between steel plates due to some areas being unwelded. Engine compartment noise: There are many possible causes for noise here. A high-pitched belt squeal is generally caused by belt slippage. Transmission noise: If there is abnormal noise inside the transmission while the car is moving, and it disappears when the clutch is pressed, it indicates that the noise source is a transmission fault, possibly caused by worn transmission bearings or gears.
I've been driving for over a decade and encountered many low-speed noise issues. When a Corolla has problems at low speeds, it's mostly due to worn brake pads – you'll hear squeaking when starting or stopping, sometimes because the pads are too thin or have dust trapped. Another common cause is aging suspension components like shock absorbers or chassis bushings, which make clunking noises over bumps. If the wheel hub bearing is damaged, you'll hear a constant humming at low speeds, which can be quite annoying. Loose steering linkage is another possibility, causing creaking sounds when turning. Don't take it lightly – I recommend getting it checked at a dealership ASAP. Last time I fixed similar issues, it only cost a few hundred bucks. Better to address small problems before they become major risks. Pay attention during routine maintenance for peace of mind and safety.
