GM 22740470 Wheel Hub, Front

You can Select Your Vehicle to check if 22740470 fits your vehicle.

First, remove the front wheel lug nuts and raise the vehicle on jackstands to remove the hub assembly. Remove the tire and on a 4WD model, take off the hub cover and use a socket combined with large breaker bar to unscrew off driveaxle/hub nut. Brake disc as well as wheel speed sensor should be pulled out of the hub after that remove the hub retaining bolts from steering knuckle as well as disc shield. In case it is necessary tap out of side to side then pull out of steering knuckle. Before fitting a new hub assembly, clean mating surfaces at steering knuckle, bearing flange and knuckle bore. Afterward fit bearing assembly into steering knuckle (or onto drive-axle for 4WD models). Put brake disc, caliper mounting bracket, caliper and wheel speed sensor back in place (for 4WD models). Reinstall driveaxle/hub nut torquing it to specifications. Lastly put back wheel on jack stands finally tighten lug nuts to specifications while lowering vehicle.

The new bearing can be installed using a bearing installer or a piece of pipe against the outer race.

To remove and install components in the front differential for 4WD systems, follow these steps: Remove the bolts securing the axle tube to the differential carrier and the nuts attaching the tube to its support bracket. Carefully remove the output shaft tube, ensuring no components fall out. Mount the tube in a vise and remove the internal components. Measure and remove the axleshaft bearing using a slide hammer and bearing remover attachment. For installation, install the bearing to the original depth using a bearing driver or socket, then install a new seal and deflector, lubricating the seal lips with grease. Carefully drive in the axleshaft, followed by the internal components. Apply RTV sealant to the tube-to-differential housing mating surface, and install the tube assembly, tightening bolts and nuts to specified torques. Reinstall the driveaxle, front axle shift motor, and fill the differential with lubricant.

The bearings should be adjusted by tightening the adjusting nut to 50 ft-lbs, then backing it off and tightening it hand-tight.

1. Install the bearing with the square shoulder facing in, using a bearing driver or a socket with an outside diameter slightly smaller than that of the bearing. 2. Install a new seal and deflector, lubricating the lips of the seal with multi-purpose grease. 3. Carefully drive in the axle shaft with a soft-face hammer. 4. Fill the differential with the proper lubricant. 5. Install the driveaxle and differential carrier splash shield. 6. Install the wheel and lug nuts. 7. Lower the vehicle. 8. Tighten the lug nuts to the proper torque specifications. 9. Check for proper operation.

After discarding the oil seal, all components should be cleaned and inspected for wear or damage.

Clean the mating surfaces on the steering knuckle, bearing flange, and knuckle bore.

The old bearing can be extracted from the housing using a bearing puller and slide hammer.
