Abstract: An axle assembly and method of assembly. The axle assembly may include a drive pinion and a preload nut. The drive pinion may have a recess. The preload nut may have a deformable ring. The deformable ring may engage the drive pinion inside the recess to inhibit rotation of the preload nut.
Abstract: An axle assembly that includes a barrel cam. The barrel cam may be rotatable about a barrel cam axis and may be operatively connected to a first shift collar. Rotation of the barrel cam about the barrel cam axis may control movement of the first shift collar along a first axis.
Abstract: An axle assembly having an electric motor module, a drive pinion, a planetary gear set, and at least one one-way freewheel clutch. The planetary gear set may operatively connect the electric motor module and the drive pinion. The one-way freewheel clutch may be configured to selectively couple at least two components of the planetary gear set.
Abstract: A brake assembly having a guide pin assembly that slidably couples a brake caliper to a brake carrier. The guide pin assembly may include a resilient member that extends between a bushing and a sleeve. The sleeve may be mounted to the brake carrier. The brake caliper may be slidable along the bushing.
Abstract: A suspension system having a knuckle carrier. A pivot mechanism may pivotally couple a control arm to the knuckle carrier. The pivot mechanism may include a preload nut that may exert a preload force on a bearing assembly. A platform may be fixedly disposed on the knuckle carrier. The platform may support an air spring and may have an arm that is coupled to a stabilizer bar subassembly.

Abstract: An axle assembly having an electric motor module that may be operatively connected to a planetary gear set. A lubricant catching ring may be mounted to a planet gear carrier of the planetary gear set. A deflector may deflect lubricant through a lubricant opening in a wall of a shift mechanism housing.
Abstract: A planetary gear set having a planet shaft that extends from a planet gear carrier into a hole in a planet gear. At least one set of bearing rollers may be received inside the hole and may rotatably support the planet gear on the planet shaft. A first shaft thrust washer may extend between the planet gear carrier and a set of bearing rollers.
Abstract: An axle assembly that includes first and second hanger brackets and at least one cross brace. The first and second hanger brackets may be spaced apart from each other and may be adapted to be mounted to a chassis of a vehicle. The cross brace may extend from the first hanger bracket to the second hanger bracket.
Abstract: A brake assembly having a sensor assembly that is received inside a shaft of a wear adjuster mechanism. The wear adjuster mechanism may be at least partially received inside a piston that may be rotatable about the axis and may be at least partially received in a tappet. The sensor may provide a signal that is indicative of rotation of the shaft.
