This outline provides a general overview. Consult a repair manual specific to your 2001 S10 4WD for detailed instructions, torque specifications, and diagrams. These specs are crucial for safety and proper operation.
Tools You'll Likely Need:
* Wheel Hub Nut Socket: A large socket (usually 32mm or 36mm) specifically designed for this nut. This nut is often very tight.
* Impact Wrench (Highly Recommended): Essential for removing the wheel hub nut. A breaker bar might work, but it will be incredibly difficult.
* Jack and Jack Stands: Securely support the vehicle. Never work under a vehicle supported only by a jack.
* Lug Wrench: To remove the wheel.
* Wheel Puller: May be needed to remove the wheel hub from the spindle.
* Bearing Race and Seal Installer/Remover Set: Crucial for installing and removing the bearings and seals without damage. These are usually specific to the bearing size.
* Large Hammer (or a dead blow hammer): Might be needed for stubborn components.
* Torque Wrench: Essential for tightening components to the manufacturer's specifications.
* Penetrating Oil (PB Blaster or similar): To help loosen rusted or seized components.
* Pry Bar: May be helpful for separating components.
* Socket Set and Wrenches: A variety of sizes will be needed.
* Clean Rags: To keep everything clean.
* Grease: The correct type of bearing grease for your vehicle.
* New Wheel Bearings and Seals: Purchase the correct parts for your specific vehicle from a reputable parts supplier.
General Steps (Consult your repair manual for precise steps and torque specs):
1. Safety First: Disconnect the negative battery terminal. Secure the vehicle with jack stands. Chock the rear wheels.
2. Remove the Wheel: Remove the wheel and tire assembly.
3. Remove the Caliper and Rotor: Remove the brake caliper and rotor. Secure the caliper out of the way to prevent damage to the brake line.
4. Remove the Wheel Hub Nut: Use an impact wrench to loosen and remove the large wheel hub nut. This is often extremely tight.
5. Remove the Wheel Hub Assembly: This may require a wheel puller depending on the condition of the bearings and the amount of rust/corrosion.
6. Remove the Old Bearings: Use the bearing race and seal installer/remover set to carefully remove the old bearings and seals from the hub and knuckle.
7. Clean and Inspect: Thoroughly clean the hub and knuckle. Inspect the spindle for damage.
8. Install New Bearings and Seals: Use the bearing race and seal installer/remover set to carefully install the new bearings and seals, ensuring they are properly seated and lubricated.
9. Reassembly: Reinstall the wheel hub assembly, rotor, caliper, and wheel. Tighten everything to the correct torque specifications (found in your repair manual).
10. Torque Specifications: This is critical. Incorrect torque can lead to premature bearing failure or damage to other components. Use a torque wrench and follow your manual.
11. Test Drive: After reassembly, test drive the vehicle to ensure proper operation. Listen for any unusual noises from the wheel bearings.
Important Considerations:
* ABS Sensor: If your S10 has an ABS system, you'll need to be careful with the ABS sensor. It's usually located on the knuckle.
* Parts: Buy high-quality replacement bearings and seals. Don't skimp on parts.
* Repair Manual: This is essential. It will provide specific instructions, torque specs, and diagrams for your vehicle. Don't try to do this without one.
This is a complex procedure. If you are not comfortable with automotive repair, it's best to take your vehicle to a qualified mechanic. Incorrectly installed wheel bearings can lead to serious accidents.
