Tools You'll Likely Need:
* Repair Manual: Absolutely essential for torque specifications and detailed procedures.
* Jack and Jack Stands: Safety first! Never work under a vehicle supported only by a jack.
* Wheel Chocks: For added safety.
* Lug Wrench: To remove the wheel.
* Wheel Hub Socket: Usually a large, deep socket, sometimes a special hub nut socket.
* Impact Wrench (Highly Recommended): Makes removing the hub nut much easier. A breaker bar and considerable muscle are alternatives, but risk damaging the nut.
* Ball Joint Separator: To separate the ball joint from the steering knuckle. Several types exist; a pickle fork is often used but can damage the ball joint.
* Hammer and Punch: For various tasks, possibly including driving out the bearing race.
* Press (Ideally): For safely removing and installing the bearing. This is the most crucial tool if you don't want to damage the new bearing. You *can* try other methods, but it's risky.
* New Wheel Bearings and Seals: Get the correct parts for your specific vehicle.
* Grease: High-quality wheel bearing grease.
* Torque Wrench: Crucial for tightening bolts to the correct specifications.
* Penetrating Oil (PB Blaster, etc.): To help loosen rusted or seized components.
* Various Wrenches and Sockets: Sizes will depend on your specific vehicle.
General Steps (Consult Your Repair Manual for Detailed Instructions):
1. Safety First: Engage the parking brake, chock the rear wheels, and jack up the front of the truck safely using jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Disconnect Brake Caliper: Remove the caliper bolts and carefully hang the caliper out of the way, securing it so it doesn't hang by the brake line.
4. Disconnect ABS Sensor (If Applicable): If your vehicle has an ABS sensor, disconnect it carefully.
5. Remove the Rotor (or Disc): Remove the rotor (or disc brake) retaining bolts if necessary.
6. Disconnect the Ball Joint: This is often the trickiest part. Use a ball joint separator to carefully separate the ball joint from the steering knuckle.
7. Remove the Hub Nut: Use an impact wrench to remove the large hub nut. This is extremely tight and may require significant force.
8. Remove the Axle Nut and Hub Assembly: Once the hub nut is off, the hub assembly (containing the bearing) should slide off the axle.
9. Bearing Removal and Installation: This is where a press is highly recommended. The old bearings need to be carefully pressed out and the new ones pressed in, ensuring they are seated correctly. Improper installation can lead to premature bearing failure and potential damage to the hub.
10. Install New Seals: Install new seals as needed.
11. Reassemble: Reassemble everything in reverse order, ensuring all bolts and nuts are torqued to the correct specifications (as listed in your repair manual). This includes the hub nut, axle nut, and all other components.
12. Brake Caliper Reinstallation: Reinstall the brake caliper, making sure the brake pads are correctly seated.
13. Torque Specs: Absolutely crucial! Use a torque wrench to tighten all bolts to the manufacturer's specifications.
14. Test Drive: After reassembly, carefully test drive the vehicle and listen for any unusual noises.
Important Considerations:
* Rust and Corrosion: If your truck is older, rust and corrosion can make this job significantly harder. Penetrating oil is your friend here.
* Hub Bearing Type: There are different types of wheel bearings. Knowing your specific type will help you find the correct replacement.
* Professional Assistance: If you are uncomfortable with any part of this process, it's best to take your vehicle to a qualified mechanic. Improperly installed bearings can lead to serious safety issues.
This is a simplified overview; always consult your repair manual for the specific procedures and torque specifications for your 1999 Dodge Dakota. Improper repair can result in damage to your vehicle or injury to yourself. Proceed with caution and if in doubt, seek professional help.
