A shroud for a heavy-duty vehicle component that includes structure enabling the component to be mounted and housed within an interior space of the shroud, such that the component is substantially enclosed and protected when the shroud is mounted on the heavy-duty vehicle frame. In one embodiment, the component is a valve of a pin release/locking system of a moveable subframe. The shroud enables mounting of the component in a location within the interior space of the shroud that provides relatively safe, sufficient clearance for components of a forward mounted down-stop employed in some axle/suspension systems depending from the heavy-duty vehicle frame. The shroud includes structure that enables the shroud to be temporarily attached to a heavy-duty vehicle moveable subframe during shipping at a location on the subframe so that the component and associated structure are within the longitudinal length of main members of the subframe.
A disc brake hub and rotor assembly for a heavy-duty vehicle. The disc brake hub and rotor assembly includes a hub receivable on and rotatable about an axle spindle of a heavy-duty vehicle. A rotor is connectable with the hub for rotation with the hub. The rotor includes a disc segment, a flange mounting segment, and a cylindrical sleeve segment connecting the disc segment and the flange mounting segment. A flange is connectable with the flange mounting segment and separately with the hub. The flange mounting segment of the rotor has an inboard facing surface at least part of which is for engaging head portions of wheel studs. The inboard facing surface is substantially planar and free of wheel stud clearance reliefs. A transition region is located between the flange mounting segment and sleeve segment and is also free of wheel stud clearance reliefs.
A hubcap for a heavy-duty duty vehicle that includes mounting structure that is formed with and cooperates with a side wall of the hubcap to provide a stiff, rigid structure that enables non-cantilevered connection to a wheel hub. The mounting structure can be a plurality of elongated bosses circumferentially spaced about the side wall that are formed with corresponding elongated bolt openings to enable the non-cantilevered attachment to the wheel hub. The elongated bosses cooperate with the hubcap side wall to provide a stiffened or rigid structure between the elongated bolt openings for increased and more uniform clamping force on a sealing gasket between the hubcap and the wheel hub. The hubcap profile provides clearance for removal of an outboard mounted disc brake rotor in heavy-duty vehicle wheel end assemblies that include such rotor configurations. The hubcap may support simple mounting of a hubodometer.

PROCESS FOR MANUFACTURING A LEAF SPRING AND INSERT FOR LEAF SPRING
An insert to a mold for a leaf spring comprises a substrate and a hole that extends through the substrate, A post protrudes from the substrate such that the insert, may be coupled to the mold. Further, the post covers the hole on a first end, so the hole is not exposed. On the other end of the hole, a thin overlay that covers the hole. Thus, during a process where resm is added to the mold, no resin enters the hole. The insert, when added to a leaf spring, offers reinforcement on areas where there is high stress. Therefore, holes may be added to a leaf spring at areas of high stress without overly weakening the leaf spring.
