The Dana Spicer 820561-3021 or 8205613021 driveshaft is a drive shaft assembly that connects drivetrain parts too distant, or too mobile relative to each other, to be joined directly. Universal joints, and sometimes a sliding spline joint, are the usual way such a shaft keeps turning through changes in angle and length. A worn joint or coupling typically gives itself away with clicking or grinding underneath, a clunk when you get on the power, or vibration felt through the cab. If you are matching this shaft to a specific unit, call us and we will help confirm proper fit. A genuine Dana Spicer part from Pro Gear and Transmission.
