Abstract: A slip yoke assembly for a vehicle drive train assembly includes a yoke shaft having a shaft portion with a plurality of external splines formed thereon. A hollow transition member having a plurality of internal splines is connected to the yoke shaft for rotational driving movement, yet is permitted to move axially relative thereto. A hollow weld ring is secured to the yoke shaft for rotational movement therewith. The weld ring extends co-axially about the splined connection between the transition member and the shaft portion of the yoke shaft and provides an exterior surface to which one or more balance weights may be secured. The weld ring also provides an annular space to retain a quantity of lubricant for the splined connection. A flexible convoluted boot is provided to seal the splined connection between the transition member and the shaft portion of the yoke shaft. A first end of the boot is secured to the weld ring, while a second end of the boot is secured to the transition member.
