Nissan 40215-A0100 BEARNG-Wheel

Lift up the vehicle with the jack and firmly put it on jackstands, finally, take off the wheel. First, undo the bolts which hold the brake caliper on and then unscrew the dust cap and follow this by removing the O-ring. Remove the cotter pin and take the locking cap off of the wheel bearing nut on the wheel bearing. Lose the wheel bearing nut and washer on the spindle and unscrew the hub and the rotor; beware of the outside bearing falling off. Place the rotor in a face down manner on a work bench and then, with a screw driver, loosen the inner bearing grease seal to get its removal, together with the inner bearing. Scrape out all remnants of the old grease from the bearings, hub, as well as spindle before washing the area with parts solvent, check the condition of the bearings and if they show signs of wearing, replace them. If the bearing race is also worn or damaged, remove this also, with a brass drift for the bearing race out of the hub, and fit a new one together with the new bearing. Place a new race by using a socket to start screwing it into its seat with the addition of wheel bearings and bearing races being bought and installed as a set. To the bearings coat high-temperature front-wheel bearing grease and make sure that the grease is worked into the bearings completely. Apply a thin coat of grease to the spindle at various seats afterwards insert the inner bearing into the back of the hub and working a bit of grease. Apply some paste on the inner part of the seal lip, align the new seal over the inner bearing and push it and get it to be flush with the hub. Ensure that prior to the assembly of the hub into the spindle, the outer bearing carrying the grease pack is properly located and the hub before being fitted should be fully filled with grease. Place the washer with the adjuster nut, tightening it and rotating the rotor in clockwise & counter clockwise to press the bearings. After tightening the adjuster nut to the torque indicated earlier, turn the adjuster nut counterclockwise by sixty degrees to achieve the right pre-load. Replace the adjusting cap and use a new cotter pin, subsequently, use the dust cap with a new O-ring. Last of all, take of the jackstands and release the vehicle down.

Generally, the wheel bearings will require infrequent service; however, they should be checked whenever the wheels are raised for any reason. With the vehicle securely supported on jackstands, spin each wheel and check for noise, rolling resistance, or free play. Grasp the top of the tire with one hand and the bottom with the other, then rock the tire on the spindle. If the wheel moves, indicating side play, the bearings should be removed, inspected, and replaced if necessary. Remove each wheel and tire, and inspect the area around the bearings for grease leaking past the wheel bearing seals, which must be replaced if any leakage is apparent.
