  Q: How to service front wheel bearings on Mercury Zephyr?

  A: In most cases, the front wheel bearings will not need servicing until the brake pads are changed. However, these bearings should be checked whenever the front wheels are raised for any reason. With the vehicle securely supported on jack stands, spin the wheel and check for noise, rolling resistance or free play. Grasp the top of the tire with one hand and the bottom of the tire with the other. Move the tire in and out on the spindle. If it moves more than 0.005 in, the bearing should be checked, then repacked with grease or replaced as necessary. To remove the bearings for replacing or repacking, begin by removing the hub cap and wheel. Remove the grease cap, using a screwdriver. Straighten and remove the cotter pin and remove the nut lock. With an adjustable wrench or channel-lock-type pliers, remove the lock nut. Remove the flat washer. Grasp the brake rotor firmly and with a slight rocking motion, withdraw the hub from the spindle. Inspection and packing procedures for the wheel bearings can be found. Installing is the reversal of removal but the wheel bearings must be adjusted before the nut lock and cotter pin are fitted. Install the lock nut finger tight and then rock the hub assembly in and out several times to push the brake pads away from the rotor. Install the wheel. While rotating the wheel and hub assembly, tighten the nut to 17 to 25 ft-lb (10 to 15 Nm) to seat the bearings. Loosen the nut one-half turn and then retighten to 10 to 15 lb-in(1.1 to 1.7 Nm). Install the nut lock on the nut so that the castellations on the lock align with the spindle cotter pin hole. Install the cotter pin, bending the ends around the flange of the nut lock. Spin the wheel and hub assembly to check for proper operation. Reinstall the grease cap, using a punch to lock it in position.
