The present invention involves a detachable half shaft assembly of a vehicle wheel end and has a shaft bell and a disc rotor. The detachable half shaft comprises a preloaded bearing assembly and a detachable body receiving the preloaded bearing assembly. The preloaded bearing assembly has an inner surface formed through inboard and outboard ends thereof. The detachable body has an inboard interface at an inboard end and an outboard interface at an outboard end. The inboard interface is configured for connecting to the shaft bell and the outboard is configured or connecting to the disc rotor.
