Can Half Shaft Failure Cause Transmission Abnormal Noise and Jerking?
2 Answers
Only severe damage to the half shaft can cause transmission jerking. A faulty car half shaft will produce a metal friction sound or a metal clashing sound, mostly leading to transmission abnormal noise and resonance. If abnormal noise occurs while the vehicle is in motion, it is likely due to half shaft damage. If a clunking sound is heard while driving, it indicates abnormal wear of the half shaft CV joint. The half shaft of a car is a type of drive shaft responsible for transmitting power to the wheels on both sides of the same axle. Without the half shaft, power cannot be delivered to the wheels. The half shaft of a car is equipped with a CV joint. If the CV joint experiences abnormal wear, the car will produce a clunking noise while driving. The cause of abnormal wear in the CV joint is insufficient lubrication.
A faulty driveshaft can indeed cause transmission jerking and abnormal noises, which I've personally experienced. As a car enthusiast, I know the driveshaft is responsible for transferring power from the transmission to the wheels. When damaged—such as from bearing wear or shaft deformation—power delivery becomes uneven. This causes the transmission gears to experience rapid load changes, resulting in jerking or clunking noises. These issues become particularly noticeable during acceleration or turning. Common symptoms include jerking during startup and increased noise levels. If ignored, the transmission itself may sustain damage. I believe it's crucial to inspect the driveshaft's condition promptly and replace components when necessary to prevent cascading failures. Don't wait until complete failure occurs—addressing it early ensures both safety and cost savings.
