Venting systems and methods are provided for a splined driveshaft to continually equalize the internal driveshaft pressure with that of the atmosphere, preventing at the same time, external elements, such as, water, dirt, or salt from getting into the driveshaft, thereby causing premature wear or corrosion. One venting system comprises a vent defined in a splined driveshaft for allowing air outside the driveshaft, containing telescopically resident first and second members, to pass into at least one of the first and second members, and a plug mounted over the vent. Another venting system comprises a weld yoke at an end of a splined driveshaft, a vent defined in the weld yoke allowing air outside the splined driveshaft to pass into the driveshaft, and a plug mounted over the vent. A venting method comprises providing a splined driveshaft, forming a vent defined in the splined driveshaft, mounting a plug over the vent, and venting the splined driveshaft through the vent.

A driveshaft assembly includes a male shaft and a female shaft slidably engaged with the male shaft. The shafts absorb energy during axial deformation of the driveshaft while substantially maintaining radial alignment of the male and female shafts.
