The present invention concerns an axle unit comprising a stub axle and an axle tube, wherein the stub axle has a longitudinal channel which extends inside the stub axle substantially along a stub axis, wherein the stub axle has a transverse channel which extends inside the stub axle substantially transversely to the stub axis and opens to the environment at the outer face of the stub axle, wherein the longitudinal channel and the transverse channel are connected together, wherein the stub axle has a stub joining region to which the hollow-bodied axle tube can be secured.

A broken axle recovery apparatus that provides a temporary solution for a broken semi floating rear axle shaft has a wheel hub, a backing plate and a bearing. The wheel hub is rotatably engaged with the backing plate via the bearing in such a way that the broken axle recovery apparatus enables a rear wheel to be functionally mounted onto a vehicle. The backing plate is mounted to an axle housing of the vehicle, and the rear wheel is rotatably mounted to the wheel hub. The bearing enables the wheel hub and the rear wheel to freely rotate about the axle housing so that the vehicle can be safely driven into a safe location or a mechanic shop.

An axle unit comprising a first suspension arm element and a second suspension arm element, wherein the first suspension arm element and the second suspension arm element can be mounted on a vehicle frame so as to be pivotable about a common pivot axis, wherein the first suspension arm element has a first joining region configured as a recess, and the second suspension arm element has a second joining region configured as a recess, wherein the first joining region and the second joining region are arranged on two opposing sides of an axle tube extending substantially along a tube axis, and wherein the axle tube can be secured by substance bonding in the first and second joining regions to the first and second suspension arm elements.

A removable spindle assembly improvement comprised of a spindle housing end unit having a threaded cavity. A corresponding threaded removable spindle is torqued into the threaded cavity. The spindle has a tapered section that includes O-rings for creating a seal along the corresponding section of the cavity to prevent corrosion which assists in the elimination of spindle seizure within the spindle housing end unit's cavity. The spindle housing end unit's housing includes at least two threaded apertures that cooperate with sealed set screws for securing the spindle in place during operation. The set screws are placed apart at an odd number of 15 degree increments. This assembly facilitates easy removal and replacement of a spindle on a spring axle.
