An adjuster mechanism and an axle assembly that includes an adjuster mechanism. The adjuster mechanism may include a collar assembly that has a collar that may receive a shift collar, a follower, and an adjustment screw. Rotating the adjustment screw may move the collar assembly and the shift collar along an axis.

A method of making an interaxle differential unit. The method may include piercing a workpiece and then ring roll forging the workpiece to form an annular case that is a seamless ring. The annular case may be heat treated before installing an interaxle differential unit gear nest inside the annular case.

An actuator is used to longitudinally move a spline sleeve for controlling drive mode of a differential on an off-road vehicle. The actuator's motor rotates an eccentric knob through a drive train including intermediate gears and a worm gear. The eccentic knob is linked to the spline sleeve through a torsion spring carried on a pivot plate, with legs of the torsion spring pushing a slide block, transferring a moment provided by the eccentric knob into a linear slide force. The pivot plate and torsion spring are jointly mounted on the actuator housing by a hub, opposite the rotational axis of the eccentric knob from the slide block. The slide block includes a contact which completes a circuit through conductive pads on the actuator housing, so the position of the slide block can be directly sensed.

A differential reducer for a motor vehicle, including: a differential mechanism including a ring gear; a reduction mechanism including a secondary pinion and a primary pinion; a crankcase including a first half-crankcase and a second half-crankcase, of which an internal transverse wall of each half includes three bearing seats, each internal transverse wall having first means for collecting and directing oil sprayed by the ring gear, which means turn in a first direction of rotation to the bearing seats; wherein each internal wall includes second means for collecting oil which is sprayed substantially transversally through rotation of the ring gear in a second direction of rotation.
