A power-assisted steering system includes a control shaft (102) arranged along a control shaft axis (104). An assist drive shaft (108) defines a drive shaft axis and is arranged in a plane that is substantially transverse to the control shaft axis (104). The assist drive shaft (108) is supported relative to the vehicle structure (106) by a first bearing assembly (112) and a second bearing assembly (114). A worm (118) is disposed about the assist drive shaft (108). A worm gear (120) is coupled to the control shaft (102), and the worm gear (120) and control shaft (102) are configured for rotation about the control shaft axis (104). The worm gear (120) is configured for engaging the worm (118) such that rotation of the worm (118) and the assist drive shaft (108) about the drive shaft axis causes rotation of the worm gear (120) and the control shaft (102) about the control shaft axis (104). The first bearing assembly (112) is configured as an eccentric bearing assembly.
