Why does the Corolla make a clicking sound when jerking at low speed acceleration?
2 Answers
Corolla making a clicking sound when jerking at low speed acceleration is due to transmission jerking, and there might be some issues with the transmission. Check if the rear wheel bearings are damaged or if the bearings are loose inside the hub: Inspect whether the drive chain and sprocket are excessively worn or if the chain is overly stretched. Check if the chain adjustment is consistent on both sides and if the brake spring and brake pads are damaged: After lifting the car, the sound might disappear due to the reduced load. You can check all the above-mentioned areas. If the bearings are damaged or there are other mechanical faults, abnormal sounds will generally occur regardless of whether the car is cold or hot, at low or high speed, or with large or small throttle.
I've noticed the issue of jerking and clunking sounds when accelerating at low speeds in the Corolla, and I've experienced similar situations with several other cars I've driven. This is usually caused by automatic or CVT transmissions, where unstable oil pressure at low speeds leads to jerking sensations, and the clunking sounds may come from a loose driveshaft or differential. Long-term neglect can exacerbate component wear, making repairs more expensive. I recommend first checking if the transmission fluid needs to be replaced, as its degradation can affect lubrication, and then inspecting the engine mounts for cracks. Avoiding sudden acceleration and deceleration during daily driving can help alleviate the symptoms. It's best to visit a professional repair shop as soon as possible for a diagnostic scan to identify the specific cause and prevent further deterioration, which could affect driving safety or fuel efficiency. Sometimes, replacing small parts can solve the problem, so don't delay until it becomes a major issue.
