Here's a general outline of the process. Remember, this is a simplified overview, and specific steps may vary depending on your vehicle's exact model and configuration. Always consult a repair manual specific to your 1998 Ford Bantam/Ranger for detailed instructions and torque specifications.
1. Diagnosis:
* Noise: The most common symptom is a humming, growling, or rumbling noise that increases with speed. This is usually more noticeable when turning.
* Play: With the vehicle jacked up and the wheel off, try to grab the wheel and move it up and down, or side to side. Excessive play indicates a worn bearing. Be careful; don't force anything.
* Heat: A hot wheel bearing is a strong indicator of a problem.
2. Preparation:
* Safety First: Jack up the vehicle securely using jack stands. Never work under a vehicle supported only by a jack. Engage the parking brake.
* Gather Tools: You'll need a jack, jack stands, wheel chocks, lug wrench, socket set (metric), bearing puller (specific type for your vehicle), hammer, grease, new wheel bearing, possibly a press (depending on the type of bearing), and a torque wrench.
* Consult a Repair Manual: This is crucial. It will have specific instructions, torque specifications, and diagrams for your vehicle.
3. Removal:
* Remove the Wheel: Loosen the lug nuts, jack up the vehicle, secure it on jack stands, and remove the wheel.
* Remove the Brake Caliper and Rotor/Drum: The method varies depending on whether you have disc or drum brakes. Support the caliper with a wire or clamp to prevent damage to the brake line.
* Remove the Hub Assembly: This usually involves removing cotter pins, nuts, and possibly other components. Your repair manual will guide you.
* Remove the Old Bearing: This is where the bearing puller and possibly a press come in. This is often the most challenging step and requires careful work to avoid damage.
4. Installation:
* Install the New Bearing: Carefully install the new bearing, ensuring it's seated correctly. A press may be necessary for a proper fit. Again, your repair manual is critical here.
* Reassemble the Hub Assembly: Reverse the removal steps, ensuring everything is properly aligned and tightened to the correct torque specifications.
* Reinstall the Rotor/Drum and Brake Caliper: Make sure the caliper is properly seated and the brake pads are properly contacting the rotor/drum.
* Reinstall the Wheel and Tighten Lug Nuts: Tighten the lug nuts to the manufacturer's specified torque.
5. Post-Installation:
* Lower the Vehicle: Carefully lower the vehicle.
* Test Drive: Take a short test drive to check for any unusual noises or vibrations.
* Recheck: After a short drive, recheck the lug nuts to ensure they are still tight.
Important Considerations:
* Type of Bearing: Wheel bearings come in different types (tapered roller, ball bearings). Make sure you get the correct replacement part for your vehicle.
* Press: Many wheel bearing replacements require a hydraulic press to properly seat the new bearing. If you don't have access to one, take it to a mechanic.
* Torque Specifications: Incorrect torque can damage components or lead to failure. Always use a torque wrench and follow the specifications in your repair manual.
This is a complex repair. If you're unsure about any step, take your vehicle to a qualified mechanic. Improperly installed wheel bearings can lead to serious accidents. A repair manual specific to your 1998 Ford Bantam/Ranger is absolutely essential for successful completion.
