Driveshaft assembly and method for assembling driveshaft assembly

A driveshaft assembly for a vehicle configured to transfer torque from a first component of a torque tube assembly to a second component of the torque tube assembly, the driveshaft assembly comprising:

• a tube having a first end and a second end;
• a first member having a first end with an engaging surface configured to transmit torque to the first component and a second end configured to be coupled to a substantially parallel surface at the first end of the tube;
• and
• a second member having a first end with an engaging surface configured to transmit torque to the second component and a second end configured to be coupled to a substantially parallel surface at the second end of the tube;
• wherein the first member and the second member are configured to have axes of rotation that are collinear with an axis of rotation of the tube when the first member and second member are coupled to the tube;
• wherein the engaging surface of the first end of the first member and the engaging surface of the first end of the second member each have a surface variation of less than 0.20 mm relative to the axis of rotation of the tube after being coupled to the tube.
