However, if you are experienced and equipped, here's a general overview of the process. This is NOT a complete, step-by-step guide, and variations may exist depending on your specific truck's configuration. Always consult a repair manual specific to your year and model for detailed instructions and torque specifications.
Tools and Materials You'll Need (at a minimum):
* Repair Manual: Absolutely essential for specific torque specs and procedures.
* Wheel Hub and Bearing Press: This is crucial for safely pressing the old bearings out and the new ones in. Improvised methods are highly discouraged.
* Socket set and wrenches: Various sizes will be needed.
* Jack and jack stands: Safety first!
* Torque wrench: For proper tightening of bolts.
* Pry bar: May be needed to help separate components.
* Hammer (soft-faced): To help seat components, if needed.
* New front wheel bearings and seals: Order the correct parts for your specific truck. Get high-quality replacements.
* Grease: Appropriate grease for wheel bearings.
* Clean rags and shop towels: To keep things clean and prevent contamination.
* Penetrating oil (PB Blaster, etc.): To help loosen rusted or seized parts.
General Steps (Highly Simplified):
1. Safety First: Disconnect the battery's negative terminal. Secure the truck on jack stands after safely raising it.
2. Remove the Wheel and Brake Caliper: Remove the wheel, then carefully remove and support the brake caliper. Some models require disconnecting the brake line.
3. Remove the Rotor (if applicable): Depending on your setup, you might need to remove the brake rotor.
4. Remove the Hub Assembly: This often involves removing several bolts and possibly a cotter pin securing the castle nut. You may need to use a puller to separate the hub from the knuckle.
5. Press Out the Old Bearings: Use the bearing press to carefully remove the old wheel bearings from the hub and knuckle.
6. Clean and Inspect: Thoroughly clean the hub and knuckle. Inspect the parts for any damage; replace as needed.
7. Pack New Bearings with Grease: Pack the new bearings with the appropriate grease.
8. Press In the New Bearings: Use the bearing press to carefully install the new bearings into the hub and knuckle.
9. Reassemble: Carefully reassemble the hub assembly, rotor (if applicable), caliper, and wheel, ensuring proper alignment and tightening to the manufacturer's specifications (from your repair manual).
10. Torque Everything Properly: Use the torque wrench to tighten all bolts and nuts to the correct specifications. Incorrect torque can lead to failure.
11. Lower the Vehicle: Lower the vehicle carefully and check for any leaks or binding.
12. Test Drive: Perform a test drive, paying close attention to any unusual noises or vibrations.
Again, this is a very simplified overview. Each step involves multiple sub-steps, and mistakes can be costly. Use a repair manual specific to your 2002 Dodge Ram 1500. If you're not completely confident in your abilities, seek professional help. Replacing front wheel bearings incorrectly can lead to loss of control and serious injury or accident.
