ABSTRACT:
A steerable drive axle is disclosed having a cramp angle of about 45.degree. for providing a short radius of turn for a vehicle. A trunnion assembly for each wheel includes upper and lower bearing units each having a spherical bearing and a king pin with a longitudinal axis. Axial misalignment of the king pins is corrected by the spherical bearings for enabling the upper and lower roller bearings to rotate about a common axis thereby minimizing bearing wear.
