An apparatus for use in connecting a cover member to a retaining member coupled to a nut mounted to a shaft includes a body portion, arms, and a plurality of pressing members. The arms extend from the body portion relative to the nut such that contacting portions of the arms contact a rear side of the nut to connect the body portion to the nut. The plurality of pressing members extend from the body portion and is alignable with the plurality of tabs of a cover member when the cover member is located between the body and the nut. The body portion includes a press mechanism configured to cause a first pressing member of the pressing members to contact a first tab of the cover member to deform the first tab toward a retaining member coupled to the nut mounted on the shaft.

A method for preloading a bearing includes releasably, threadably, and directly attaching an attaching member to a circumferential outside surface of an exposed end of a threaded shaft of an axle or spindle. A frame is axially separated from, and coupled to, the attaching member. A plurality of extensions extends from the frame axially past the attaching member toward the wheel hub assembly. An adjustment mechanism moves the frame and the plurality of extensions axially towards the wheel hub assembly to contact the wheel hub assembly and/or the bearing to apply a preload to the bearing within the wheel hub assembly.

A method of assembling a bearing assembly includes fitting a first ring onto a first end of a gear shaft. A second ring is fed into a slot in the first ring. The second ring is driven through the slot in the first ring. The second ring is positioned within the first ring. The second ring is positioned about the gear shaft such that a first end and a second end of the second ring are covered by a solid portion of the first ring.

A pinion needle roller bearing post for use during pinion gear carrier assembly includes a solid cylindrical post having a longitudinal surface wall extending between a first end and a second end. At least one radially recessed channel is disposed in the longitudinal surface and extends substantially between the first end and the second end and a spring biased needle roller is disposed within the at least one radially recessed channel that operates to prevent needle roller bearing skew during pinion gear carrier assembly.

A lock nut system includes a nut threadably engageable with a shaft and a keeper having a projection configured to fit within a slot of the shaft to engage the shaft. A retaining member is formed separate from the keeper and the nut. The retaining member is receivable within a slot of the nut to engage the nut. A portion of the retaining member engages the keeper by extending into a keeper cavity within the keeper. The nut is lockable onto the shaft when the projection of the keeper is fit within the slot and the keeper is abutted and supported by an inner shoulder of the nut and the retaining member engages the nut and the portion of the retaining member extends into the cavity within the keeper.

A method includes positioning a bushing in a bore of a turbine housing; positioning a shaft of a wastegate in a bore of the bushing where the shaft includes a shaft shoulder and a shaft end; applying force to a plug of the wastegate to substantially center the plug with respect to a wastegate seat of the turbine housing; positioning a resilient metal wire mesh ring at least in part in the bore of the bushing and between the shaft shoulder and the shaft end; encasing the ring into the bore of the bushing; and fixing a control arm to the shaft.
