  Q: How to Service and Repair the Wheel Bearing and Hub on a Motorhome on Ford Excursion?

  A:

  You need to raise and secure the vehicle first before removing the front wheel along with the tire to work on the Wheel Hub and bearing of a motorhome. Position the Brake Caliper aside first and remove the hub cap along with the gasket from the hub-rotor assembly. The spindle and nut threads should be checked for damage while removing the cotter pin and adjusting nut with flatwasher for reassembly. Extract the outer bearing cone followed by the roller assembly then pull out the hub and rotor assembly from the spindle. A slide hammer and bearing seal remover should be used carefully to pull out the inner bearing cone and bearing seal while protecting the bearing cage. The installation process starts with complete removal of old lubricant from all components followed by thorough bearing and bearing cup assessment for damage; replacing both parts when damage exists according to recommendations for new set purchase. Use a bearing cup driver tool to install both bearing cups inside the hub assembly while verifying correct seating through a 0.38-mm (0.0015-inch) feeler gauge so a piece of the gauge should not slide in. Emery cloths should be used to smooth any burrs and scratches from the spindle shoulder and seal bore in the hub. Fill the hub cavity with lithium-base wheel bearing grease such as Motorcraft Premium Long-Life Grease XG-1-C or -K, until the grease reaches the inside diameter positions of the two bearing cups. Lubricate bearing cones and rollers through the application of grease and utilize a bearing packer if possible. Position the hub spindle at the center to protect threads from damage while you insert the inner bearing cone along with rollers into the inner cup before sealing the wheel bearing hub with a proper installation. The procedure requires you to first install the rotor together with the hub assembly before adding the outer bearing cone along with roller assembly and flatwasher to the spindle. Adjust the bearing with the installing nut before finishing the adjustment with new cotter pin installation. End the procedure by installing a new gasket along with the hub cap before reattaching the front disc brake caliper and rotor as well as installing front wheel and tire assemblies then lowering the vehicle.

  Q: How to check the wheel bearings on Ford Excursion?

  A:

  The procedure for checking wheel bearings begins with hoisting the vehicle so that front tires clear floor level while the wheels point in a straight line. The air suspension switch needs to be turned off before tire work because unwanted air spring alteration can make the car move. A manual spin of the tire will help detect roughness in wheel bearings while verifying the Brake Pads are in a position that enables unhindered movement of both wheel and tire assembly. To inspect the front wheel bearing, lift the weight off it while you move the wheel through its entire width by gripping the tire at the top and the bottom. Test the tire and wheel (hub) on the spindle by checking for looseness and free rotation while avoiding roughness when spun because vehicles with inner and outer bearings will require new bearing or cup replacement to address wear and damage. This procedure requires replacement of the Wheel Hub when a vehicle only has one sealed bearing.
