Here's a general overview of the process; however, this is NOT a substitute for a proper repair manual:
Tools and Supplies You'll Need:
* Repair Manual: Absolutely essential!
* Jack and jack stands: Safety first! Never work under a vehicle supported only by a jack.
* Wheel chocks: To prevent the truck from rolling.
* Lug wrench: To remove the wheel.
* Socket set and wrenches: Various sizes will be needed.
* Impact wrench (optional but highly recommended): Makes the job significantly easier.
* Ball joint separator: To separate the ball joint from the steering knuckle.
* Tie rod end separator: To separate the tie rod end from the steering knuckle (may be integrated with ball joint separator).
* C-clamp: May be needed to compress the caliper piston.
* Caliper bracket bolt wrench: Usually a special wrench or socket is needed.
* New wheel hub bearing assembly: Make sure you get the correct part for your truck.
* Penetrating oil (PB Blaster, etc.): Helps loosen rusted bolts.
* Torque wrench: Crucial for tightening bolts to the correct specification.
* Clean rags and shop towels: Keep things clean.
* Grease: For the new bearing.
General Steps (Consult your repair manual for precise details and torque specs):
1. Safety First: Engage the parking brake, chock the rear wheels, and use jack stands to securely lift the front of the truck.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Brake Caliper: Use a C-clamp to compress the caliper piston (if needed) to allow you to remove the caliper bolts and hang the caliper out of the way.
4. Disconnect the Ball Joint and Tie Rod End: Use the appropriate separator tools to carefully separate the ball joint and tie rod end from the steering knuckle. Support the suspension components to prevent damage.
5. Remove the Axle Nut: This is usually a large nut on the end of the axle shaft. You'll likely need an impact wrench to break it loose.
6. Remove the Rotor (if applicable): On some models, the rotor may need to be removed before the hub assembly can be removed.
7. Remove the Hub Assembly: Once the axle nut and other components are removed, the hub assembly should slide off the axle. It may be tight, requiring some gentle persuasion.
8. Install the New Hub Assembly: Carefully install the new hub assembly, ensuring it's properly seated.
9. Reassemble Everything: Reinstall the axle nut, rotor, brake caliper, ball joint, and tie rod end, making sure everything is properly aligned and torqued to the specifications in your repair manual. This is where the repair manual is critical.
10. Install the Wheel: Mount the wheel and tighten the lug nuts to the correct torque specification.
11. Lower the Truck: Lower the truck from the jack stands.
12. Test Drive: Carefully test drive the truck to ensure everything is working properly.
Important Considerations:
* ABS Sensor: The ABS sensor might be integrated into the hub assembly. Be careful not to damage it during removal and installation.
* Torque Specifications: Use a torque wrench and follow the specifications in your repair manual precisely. Incorrect torque can lead to premature failure or damage.
* Bearing Pack: Some hub assemblies come pre-packed with grease. Check the instructions.
This is a simplified overview. Always consult a repair manual specific to your vehicle before attempting this repair. If you're not comfortable performing this repair yourself, take your truck to a qualified mechanic. Improperly installed wheel bearings can be dangerous.
