Drivetrain Repair FAQ
Common questions about drivetrain repair and service, answered by our ASE Certified technicians in Simi Valley.
A CV (Constant Velocity) axle transmits power from the transmission to the wheels while allowing for suspension movement. It has flexible CV joints at each end covered by rubber boots. When these joints or boots fail, replacement is needed.
A clunking noise when turning often indicates a worn CV joint. This is especially common at low speeds during tight turns. Other causes include worn tie rod ends, ball joints, or wheel bearings.
CV axles typically last 70,000 to 130,000 miles. However, if the protective CV boot tears and grease leaks out, the joint can fail much sooner. Regular inspections catch boot damage early.
