Tools You'll Likely Need:
* Wheel Hub Nut Socket: A large socket specifically designed for your Focus' wheel hub nut.
* Jack and Jack Stands: Essential for safe vehicle lift.
* Lug Wrench: To remove the wheel.
* Brake Caliper Removal Tool: To compress the caliper piston.
* Wheel Bearing Removal and Installation Tool: This is crucial and often a specific type depending on the bearing design (some are press-fit, others use a race). Avoid improvising here.
* Torque Wrench: Extremely important for tightening the hub nut to the correct specification (found in your repair manual).
* Hammer and Punch (possibly): May be needed depending on the bearing removal/installation tool.
* Penetrating Oil (PB Blaster, etc.): To loosen rusted or seized components.
* Clean rags and gloves.
* New Wheel Bearings and Seals: Get the correct parts for your specific vehicle.
General Steps (Consult your repair manual for precise details):
1. Safety First: Engage the parking brake firmly, chock the rear wheels, and use jack stands to securely lift the vehicle. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Unscrew the lug nuts and remove the wheel.
3. Remove the Brake Caliper: Use the caliper removal tool to compress the caliper piston and carefully remove the caliper assembly. Secure it out of the way, possibly hanging it from the suspension.
4. Remove the Rotor (if applicable): Depending on your Focus' configuration, you might need to remove the rotor. This often involves removing a couple of bolts.
5. Remove the Axle Nut: Use the appropriate socket to remove the large axle nut. This will likely be very tight.
6. Remove the Hub Assembly: This is where the specific bearing removal/installation tool is crucial. The hub assembly typically needs to be pressed off the spindle. The tool helps with this.
7. Remove the Old Bearing(s): The old bearing(s) are usually pressed into the hub assembly. Your removal tool will be essential here.
8. Install the New Bearing(s): Use the installation side of your bearing tool to carefully press the new bearings into the hub assembly. Make sure they are seated correctly and evenly.
9. Install the New Seals (if applicable): If your kit included new seals, install them according to the instructions.
10. Reassemble: Carefully reverse the disassembly steps, ensuring everything is correctly aligned and tightened to the proper torque specifications (found in your repair manual). Pay close attention to the axle nut torque.
11. Test Drive: After reassembly, test drive your vehicle carefully, checking for any unusual noises or vibrations.
Important Considerations:
* Pressing Bearings: Improper pressing of bearings can damage them, rendering them useless. Use the correct tool.
* Torque Specifications: Incorrect torque can lead to premature bearing failure or damage to other components. Use a torque wrench and consult your repair manual.
* ABS Sensor: If your Focus has ABS, be mindful of the ABS sensor located near the hub. Handle it carefully to avoid damage.
Disclaimer: This is a general guide. Improper repair can lead to accidents. If you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. Always consult your vehicle's repair manual for specific instructions and torque specifications.
