a bore 140 in the housing 52 the housing 52 is free to rotate about the fastener 138 the fastener 138 may include a threaded end 142 that engages a correspondingly threaded aperture 144 in the stem 100 an opposite end 146 may include a head 148 configured to enable torque to be applied to the fastener 138 for example the fastener head 148 may include an external hex 150 that can be engaged with an appropriately sized socket wrench or may include a recessed socket 152 configured to receive a suitably configured key such as a hex key or torx u2122 wrench the head 148 of the fastener 138 is disposed within the bearing cavity 61 and may be accessed through the bore 86 of the inner bearing race 54 a biasing member 154 may be disposed between the rear internal surface 66 of the bearing housing 52 and an underside of the fastener head 148 the biasing member 154 may include but is not limited to a coil spring wave spring leaf spring ring of elastic material as well as other types of biasing devices the biasing member 154 produces a biasing force that tends to draw the stem 100 and the housing 52 toward one another thereby causing the housing 52 and the stem 100 to exert a compressive force on.
