Articulable joints having diamond bearing surfaces engaged with metal bearing surfaces are provided herein. The articulable joints provide multiple degrees of freedom to components, such as drivelines, and bear loads in multiple directions. The articulable joints include diamond bearing surfaces slidingly engaged with opposing metal bearing surfaces that include more than trace amounts of diamond solvent-catalyst.

A wheel drive assembly for transferring propelling torque from a source shaft to a wheel, the source shaft receiving torque from a motion actuator. The wheel drive assembly includes a wheel-hub, adapted to have the wheel mounted thereon, the wheel-hub being arranged about a longitudinal axis, which is adapted to coincide with a rotation axis of the wheel. The wheel drive assembly further includes a drive axle and a constant velocity (CV) joint mounted onto an outer end of the drive axle. The CV joint connects the drive axle to the wheel-hub. An outermost surface of the CV joint is disposed outwardly of an outermost surface of the wheel hub, along the longitudinal axis of the wheel-hub.
