A steering gear assembly includes a pinion defining a pinion axis and a rack defining a rack axis. A bearing assembly includes a roller bearing biased against the rack to generate a normal force pressing the rack into engagement with the pinion. The bearing assembly engages an outer surface of the rack at two points circumferentially spanning a large angle to provide improved support. The roller bearing is preferably a plurality of ball bearings engaging an outer race. A deformable member may be utilized that is positioned between the outer race and the rack housing. The deformable member may comprise a series of O-rings which providing a force biasing the outer race towards the pinion.
