Tools You'll Likely Need:
* Socket set (metric and possibly SAE): Various sizes will be needed.
* Wrench set (metric and possibly SAE): Again, various sizes.
* Torque wrench: Absolutely essential for proper tightening. Incorrect torque can damage components.
* Wheel puller: To remove the wheels.
* Hub removal tool (possibly): Depending on the hub design, a special tool might be needed to remove the hub from the spindle.
* Press (likely): A shop press is almost certainly required to press out and press in bearings and seals. This is a specialized tool.
* Hammer and punch (brass punch is recommended): For carefully removing certain components.
* Penetrating oil: To help loosen rusted or seized parts.
* Grease: For repacking the bearings.
* New hub parts: This includes bearings, seals, and potentially other wear items. Order these in advance from a reputable parts supplier, specifying your truck's exact details.
* Jack and jack stands: Safety first! Securely support the vehicle.
* Wheel chocks: Prevent the truck from rolling.
General Steps (Highly Simplified):
1. Safety First: Disconnect the battery negative terminal. Securely jack up the truck and use jack stands. Engage the parking brake and use wheel chocks.
2. Remove the Wheel: Remove the lug nuts and carefully remove the wheel.
3. Disconnect Brake Caliper and Rotor: Disconnect the brake caliper and carefully secure it out of the way. Remove the rotor.
4. Remove the Hub Assembly: This step is highly dependent on the specific hub design. You might need to remove cotter pins, castle nuts, and possibly use a hub removal tool. Be careful and take pictures or make notes as you disassemble to help with reassembly.
5. Press Out Old Bearings and Seals: This requires a press and expertise to avoid damaging the parts.
6. Clean Thoroughly: Clean all components thoroughly with brake cleaner or a suitable solvent. Inspect parts for damage.
7. Install New Bearings and Seals: Use the press to carefully install the new bearings and seals in the correct order and orientation. Again, this requires precision.
8. Reassemble the Hub: Reassemble the hub assembly in reverse order of disassembly, following your notes or pictures. Pay close attention to the correct tightening sequence and torque specifications.
9. Reinstall the Rotor and Caliper: Reinstall the rotor and brake caliper, ensuring proper function.
10. Reinstall the Wheel: Mount the wheel and tighten the lug nuts to the manufacturer's specified torque.
11. Lower the Truck: Carefully lower the truck and reconnect the battery.
12. Test Drive: Test drive the truck carefully to ensure everything is working correctly.
Important Considerations:
* Hub type: Your 1999 F-350 may have different hub designs. Knowing the specific type is essential to get the right parts and tools.
* Bearing preload: Proper bearing preload is critical for longevity and proper operation. Improper preload can lead to premature bearing failure.
* Torque specifications: Following the manufacturer's torque specifications is critical to prevent damage to components.
* Safety: Working on a vehicle involves inherent risks. Be cautious and use safety glasses and gloves.
Again, this is a highly simplified overview. You absolutely need a detailed repair manual for your specific vehicle. Attempting this repair without the proper knowledge and tools can lead to damage to your truck and potentially injury to yourself. Consider the cost of professional repair versus the risk of doing it yourself incorrectly. If you lack experience, professional help is strongly advised.
