The driveshaft on front-wheel vehicles rotates at the speed of the wheels. A bent or damaged driveshaft can result in vehicle vibration. Driveshaft’s on rear-wheel vehilces the driveshaft will rotate two and a half to four times the speed of the wheels. Due to the relatively large size of the rear-wheel drive shafts and high speed, vibration is significantly increased. Waterloo Transmissions tells our customers that we service in the Akron area that other considerations that many result in vibration can include tiny dents, worn universal-joints, and missing balance weights. When a technician at Waterloo Transmissions has a customer indicate that vibration is experienced when accelerating or decelerating, the driveshaft is inspected as the most probable cause.
