Abstract: An axially adjustable driveshaft assembly in a drive train system is described. Two hollow driveshaft sections, where one has a valve through an aperture in it and each has an end fitting, engage each other to form an axially adjustable driveshaft assembly that has a sealed internal chamber within. When a pressurized air or vacuum source is connected to the valve, air fills the chamber or air is removed from the chamber, which correspondingly increases or decreases a drive train system length. This results in facilitating the installation of the driveshaft assembly between a transmission and an axle assembly in a drive train system.

Abstract: A driveshaft assembly includes a tubular slip member having a first spline member having a plurality of splines formed thereon having a first tolerance and a second spline member having a plurality of spline sections. The plurality of spline sections includes a plurality of splines formed thereon having a second tolerance. The second spline member cooperates with the first spline member. A zone is disposed on the second spline member and has a first profile. The zone is disposed adjacent to at least one of the plurality of spline sections of the second spline member, and the first profile defines a clearance relative to the first spline member.

Abstract: An axially adjustable driveshaft assembly includes a first section and a second section that engages the first section for relative axial movement. The first and second sections cooperating to define an internal chamber. A valve is provided on one of the first and second sections and provides fluid communication with the internal chamber. The valve may have a passageway portion formed therethrough and first and second sealing lip portions that normally engage one another so as to provide an air-tight seal therebetween. The axially adjustable driveshaft assembly may be installed in a drive train system by varying the pressure within the internal chamber so as to change the length defined by the axially adjustable driveshaft assembly to equal a length defined by the drive train system and installing the axially adjustable driveshaft assembly in the drive train system.

Abstract: Universal joints, and more particularly, an apparatus and method for servicing staked universal joints as well as a u-joint serviced with the method and the apparatus. The service kit includes a replacement bearing assembly, a retention assembly and a spacer sized to fit between the retention assembly and the replacement bearing assembly. The method generally includes the steps of removing the stakes from an aperture on a driveshaft, removing an original bearing assembly from the aperture, inserting the replacement bearing assembly into the aperture, inserting the spacer into the aperture and retaining the spacer and replacement bearing assembly within the aperture with the retention assembly.

Abstract: A vehicular driveshaft assembly includes a first universal joint connected to an aluminum yoke shaft having an externally splined hollow body. A first open end of an aluminum sleeve receives the splined body of the yoke shaft. Internal splines of the sleeve cooperate with the external splines of the yoke shaft body to permit axial slip between the sleeve and the yoke shaft. A second end of the sleeve is secured to a first end of a driveshaft tube. A second end of the driveshaft tube is secured to a tube yoke. The tube yoke is connected to a second universal joint.
