Abstract
A power steering assembly has a housing and a ball nut assembly supported on the housing. The ball nut assembly has a ball nut axis. The housing has a first surface between the housing and the ball nut assembly. The ball nut assembly also has a second surface. The second surface rotates on the first surface such that the ball nut assembly rotates relative to the housing on a rotation axis that is transverse to the ball nut axis.
