Tools You'll Likely Need:
* Jack and jack stands: Absolutely essential for safety.
* Lug wrench: To remove the wheel.
* Wheel chocks: To prevent the vehicle from rolling.
* Socket set and wrenches: Various sizes, including metric and possibly SAE.
* Hammer and punch: For removing the bearing race.
* Bearing race installer/remover: Makes the job much easier and reduces damage risk. A slide hammer is helpful, but a press is ideal.
* Torque wrench: Critical for proper tightening to prevent premature failure.
* Penetrating oil (PB Blaster, etc.): To help loosen rusted bolts and nuts.
* Pry bar: May be needed to separate components.
* Clean rags and shop towels.
* New wheel bearing and race(s): Make sure to get the correct part number for your specific year, model, and axle configuration (front or rear, 2WD or 4WD).
* Grease: Pack the new bearing with the appropriate grease.
General Steps (This is NOT a complete guide. Refer to your repair manual):
1. Safety First: Secure the vehicle on level ground using jack stands. Engage the parking brake and use wheel chocks. Disconnect the negative battery terminal.
2. Remove the Wheel and Brake Components:
* Remove the lug nuts and wheel.
* Remove the brake caliper (support it with wire to prevent stressing the brake line) and rotor. You may need to compress the caliper piston.
* Remove the cotter pin and castle nut securing the wheel hub.
* Remove the hub. This might require some force; use a puller if necessary.
3. Remove the Old Wheel Bearing:
* This is the most challenging part. The bearing is likely pressed into the hub. You'll need to remove the inner and outer races. This usually involves using a bearing race and seal puller and possibly a hammer and punch, working carefully to avoid damaging the hub or axle. A shop press is the best tool for this.
4. Clean and Inspect: Thoroughly clean the hub and axle housing. Inspect for any damage to the axle housing.
5. Install the New Wheel Bearing:
* Pack the new bearing with grease.
* Carefully install the new bearing races using a bearing race installer. Avoid hammering directly on the bearing.
* Press the new bearing into the hub using a press if possible, or carefully using a socket and hammer, working evenly. Again, avoid damage to the bearing.
6. Reassembly:
* Reinstall the hub onto the axle.
* Reinstall the rotor and caliper.
* Install the cotter pin and castle nut, tightening to the correct torque specification (consult your repair manual).
* Reinstall the wheel and tighten the lug nuts to the correct torque specification.
7. Test Drive: Carefully test drive the vehicle to ensure the new bearing is working correctly. Listen for any unusual noises.
Important Considerations:
* 4WD Models: Replacing wheel bearings on a 4WD Dakota is more complex due to additional components and potential for axle shaft disassembly.
* Hub Assemblies: Some later model Dakotas might use a complete hub assembly that simplifies the replacement, essentially replacing the entire bearing and hub unit as one. Check your parts compatibility.
* Professional Help: If you are not comfortable with this level of automotive repair, it's highly recommended to take your Dakota to a qualified mechanic. Improperly installed wheel bearings can lead to serious safety issues.
This is a simplified overview; consult a repair manual for detailed, year-specific instructions. Failure to follow correct procedures could result in damage to your vehicle or injury to yourself. Remember to always prioritize safety.
