Cadillac 457052 Wheel Bearing

To replace your car wheel bearings, start by hoisting or jacking up the car and securing it with jackstands. Take off the wheel and tire before you suspend the brake caliper on wire hung from up arm. After that, remove the hub dust cap, cotter pin, spindle nut and washer. Be cautious because removing it from spindles while the bearing is in a hub may have it out of its position. Pry out the grease seal to take out an outer bearing then discard old seal, pry out the inner bearing and again throw away the old seal. Repeat these steps for another wheel. Wash all parts thoroughly with solvent, check old races for any galling or scoring; if any are found drive them out of the hub using a brass drift. Lubricate new race and seat squarely into hub with suitable tool. Examine bearings for cracked cage or pitting (replace race if necessary). Clean hub and spindle, lubricate wheel bearings with high-temperature front wheel bearing grease, apply a light film of grease to spindle at bearing seats. Inboard of each bearing race in hub add grease, pack bent thorough with grease adding more inboard after placing inner bearing in hub. Install new grease seal flush with hub lubricating seal lip with thin layer of grease. Carefully install the hub and rotor assembly; place outer bearing, washer and nut then tighten spindle nut to specified torque turning wheel forward slightly by hand as you do this. Turn back nut to "just loose" position; hand tighten it then install new cotter pin for example 1/8 th inch left sticking through hole beyond other end of castle nut (not too tight). Finally install dust cap, brake caliper, wheel/tire as well as lower vehicle to ground.
