Plug-in CVJ assembly

A powertrain assembly for use in a motor vehicle powertrain system, comprising:

• an output shaft forming a cylindrical shaft surface, a radial shoulder, and a splined end,
• a CVJ assembly having an inner race, and outer race, and ball elements therebetween, the inner race forming an inside splined bore and a radial face surface, and
• a seal assembly having a boot with an outer lip affixed to the CVJ outer race and an inner lip forming first and second radial faces and an inside cylindrical surface, and wherein axial insertion of the output shaft splined end into the CVJ inner race splined bore causes boot inner lip to be expanded and frictionally engaged with the output shaft cylindrical shaft surface and wherein the boot inner lip first and second radial faces are clamped between the inner race radial surface and the shaft radial shoulder, wherein a portion of the boot inner lip is arranged radially between the output shaft and the CVJ inner race.
