Q: How to remove and install a front hub assembly on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?
A: 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.
