Driveshaft

Driveshafts transmit rotational power from the transmission or transaxle to the wheels, typically in rear-wheel drive, all-wheel drive, and four-wheel drive vehicles. These tubular components utilize universal joints or constant-velocity joints to accommodate angles and allow for suspension movement. Driveshaft construction commonly involves a steel or aluminum tube enclosing a central spline, balanced for rotational stability at high speeds. Variations include one-piece, multi-piece, and slip yoke designs to manage vehicle ride height changes and driveline vibration. Critical specifications include length, diameter, spline count, and joint type, impacting compatibility and performance.
