The first step for wheel bearing work is to raise and support the vehicle. Your first step for AWD cars is to undo the nuts on the wheel mounting bolts and then pull off the whole tire and wheel assembly. After the helper uses the brake pedal to hold the hub in place, remove the hub nut attached to the axle half shaft and move the brake rotor aside. Take out the bolts holding the hub and bearing onto the knuckle, then pull the hub and bearing off the axle half shaft. RWD also starts by removing the wheel and tire and exposed the front brake rotor. Raise the bonnet safely, remove the dust cover without damaging the hub and then unbolt the hub nut and pull the hub and bearing free from the spindle. Be certain that the isolation washer is available, without damage, before you mount the hub and bearing to the axle half shaft and put the assembly onto the knuckle. Install each bolt and tighten them to 68 Nm. Replace the rotor, caliper and adapter assembly and use someone else to assist as you install the hub nut on the rotor, then tighten it to 213 Nm. After installing the wheel and tire, set the wheel mounting nuts to 150 Nm. Next, lower the car, pump your brakes a few times for a strong brake feel, check and adjust the brake fluid and finally do a road test. Check the magnetic encoder for any harmed area and get rid of any bits of steel before setting the hub and bearing onto the knuckle spindle. Put in the hub nut and tighten it to 250 Nm, then put back the brake rotor, caliper and adapter assembly. Add a new dust cap to the outer part of the coupling, put the wheels back on, snug the mounting nuts to 150 Nm torque, lower the car, press the brake a few times, check the brake fluid level and drive the car briefly to check it functions normally.
