    Abstract: A utility vehicle is described having front and rear passenger area, and an HVAC system provides treated air to both front and rear areas. The front area includes a tunnel extending longitudinally rearwardly, and a low profile duct extends within the tunnel to communicate treated air to the rear passenger area. The frame has been modified to mount a drive shaft carrier bearing to maximize the area under the tunnel for hose routing. The frame has been modified to maximize the ingress area for the foot of the rear passenger. The frame has been modified to better seal the vehicle when doors are utilized.

    Abstract: Drivetrains and constant velocity joints for recreational vehicles are disclosed. These joints comprise a housing, an aperture for connecting with an axle, and interior components for rotatably connecting the axle to the housing. Various retention mechanisms improve the retention of constant velocity joints, including hydraulic-based, disc-based, pin-based, spline-based, and spring ring-based mechanisms. Hydraulic-based systems utilize adjustable hydraulic pressure for maintaining engagement. Disc-based mechanisms employ a conical disc that provides additional frictional force to resist pull-out forces. Pin-based retention involves drive pads or pins and corresponding tracks or grooves in the shaft interfacing gear. Spline-based mechanisms include a toolless locking half shaft retention system with rotating, interrupted splines. Spring ring-based retention features multiple flexible retaining rings placed axially along the spline, providing improved shaft retention. These retention mechanisms enhance the performance and reliability of recreational vehicle drivetrains by securing the constant velocity joint connections.
