The invention provides a steering assembly ( 10, 10 a) including a first shaft ( 28, 28 a) having a first longitudinal axis ( 29, 29 a). The steering assembly ( 10, 10 a) also includes a second shaft ( 32, 32 a) having a second longitudinal axis ( 33, 33 a). The first and second longitudinal axis ( 29, 29 a , 33, 33 a) are transverse and offset with respect one another. The first and second shafts ( 28, 28 a , 32, 32 a) are engaged at an intersection ( 35, 35 a) such that the second shaft ( 32, 32 a) translates along the second longitudinal axis ( 33, 33 a) in response to rotation of the first shaft ( 28, 28 a) about the first longitudinal axis ( 29, 29 a). The steering assembly ( 10, 10 a) also includes a bearing member ( 34, 34 a , 34 b , 34 c) contacting the second shaft ( 32, 32 a). The bearing member ( 34, 34 a) is moveable along a bearing axis ( 37, 37 a) extending transverse to both of the first and second longitudinal axis ( 33, 33 a) at the intersection ( 35, 35 a) to support the second shaft ( 32, 32 a). The steering assembly ( 10, 10 a) also includes an adjustment member ( 36, 36 a , 36 b) adjustably spaced from the bearing member ( 34, 34 a , 34 b , 34 c) along the bearing axis ( 37, 37 a). The adjustment member ( 36, 36 a , 36 b) limits movement of the bearing member ( 34, 34 a , 34 b , 34 c) along the bearing axis ( 37, 37 a). The steering assembly ( 10, 10 a) also includes a post ( 40, 40 a , 40 b , 40 c) disposed between the bearing member ( 34, 34 a , 34 b , 34 c) and the adjustment member ( 36, 36 a , 36 b) along the bearing axis ( 37, 37 a). The post ( 40, 40 a , 40 b , 40 c) prevents the bearing member ( 34, 34 a , 34 b , 34 c) and the adjustment member ( 36, 36 a , 36 b) from contacting one another.
