What Causes the Abnormal Noise When Accelerating in a Corolla?
2 Answers
Toyota Corolla acceleration abnormal noise causes: 1. Damaged or improperly installed shock absorber plane bearing. 2. Aging or damage of shock absorber rubber. 3. Severe wear of engine parts or improper assembly/adjustment. 4. Damage to components like generator or water pump. Below are more details about the engine: 1. The engine is the most crucial component of a vehicle, primarily providing power for driving, and its role is irreplaceable. 2. Daily maintenance of the engine is essential; owners should regularly clean oil stains to keep the engine clean. 3. For engine oil stain cleaning, use a damp cloth for wiping. If not fully cleaned, try using common cleaning agents. If neither method works, finally rinse with clean water.
We often encounter abnormal noises during acceleration when repairing Corollas. Most cases are caused by a loose exhaust system, especially when the exhaust pipe gasket ages, producing a metallic 'squeaking' sound during acceleration. Last time we handled a similar issue for a customer, we found all the screws on his engine guard plate were loose, causing a rattling noise at higher speeds. Aging belts are also common culprits, emitting a 'chirping' sound during cold starts and acceleration. Worn CV joints can produce a 'clicking' noise when accelerating during turns, which should be replaced promptly. The most concerning issue is a faulty transmission valve body—grinding metal sounds accompanied by jerking require immediate attention. Don't tough it out; it's safest to get the car on a lift and inspect the chassis early. I've seen cases where trapped stones wore through the exhaust pipe in just six months.
