An axle assembly of a vehicle including a differential assembly, a first axle tube including a proximal end adjacent the differential assembly, an opposite distal end, and an axle bore extending therebetween, a first axle shaft rotatably received in the first axle tube, the first axle shaft including a proximal end disposed in the differential assembly, and an opposite distal end extending outwardly from the distal end of the first axle shaft, and a radial bearing assembly including an inner cup, an outer cup and a plurality of roller elements rotatably received therebetween, the outer cup being axially fixed within the axle bore of the first axle tube and the inner cup being axially fixed to the first axle shaft.

A method and system for detecting forces and moments acting on a vehicle wheel, wherein an outer ring of a wheel hub unit has a plurality of strain sensors configured to generate first signals (Ds1) proportional to mechanical stresses on the outer ring and a temperature sensor generating a second signal (Ds2). Further, the detection system comprises a second processing unit configured to process third signals (Dv1,n) corresponding to selected vehicle state parameters; and a third processing unit that receives the third signals and the pseudo-sinusoidal signal and calculates said forces and moments on the vehicle wheel.
