That said, here's a general outline of the steps involved. Specific details may vary slightly depending on your exact model and minor variations within the 1999 Sportage EX. Always consult a repair manual specific to your vehicle for precise instructions and torque specifications. A Haynes or Chilton manual is a good investment.
Tools You'll Likely Need:
* Jack and jack stands: Essential for safely lifting the vehicle.
* Wheel chocks: To secure the vehicle while working.
* Lug wrench: To remove the wheel.
* Wheel bearing removal and installation tool: This specialized tool is crucial for safely removing and installing the bearing without damage. Trying to do it without this tool is extremely risky.
* Hammer and punch (possibly): May be needed depending on the bearing removal tool used.
* Sockets and wrenches: Various sizes, likely including metric sizes.
* Torque wrench: Absolutely essential for tightening bolts to the correct specifications.
* Penetrating oil: To help loosen rusted or seized bolts.
* Grease: For the new bearing.
* New wheel bearing: Make sure you get the correct part number for your specific vehicle.
* Clean rags or shop towels: To keep things clean.
* Safety glasses and gloves: To protect yourself.
General Steps (Consult your repair manual for precise details):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks on the wheels that remain on the ground.
2. Raise and Secure: Use the jack to lift the vehicle, placing it securely on jack stands. Never work under a vehicle supported only by a jack.
3. Remove the Wheel: Remove the lug nuts and take off the wheel.
4. Remove the Brake Caliper: Carefully remove the brake caliper and hang it securely out of the way, using a wire or bungee cord to avoid putting stress on the brake line. You may need to unbolt it from the bracket.
5. Remove the Rotor: Remove the rotor (brake disc). This may require some persuasion.
6. Disconnect the CV Joint: Disconnect the CV joint from the hub. This usually involves removing a cotter pin and castle nut, then separating the joint. This is a delicate step; take care not to damage the CV joint boot.
7. Remove the Axle Nut: Remove the large axle nut securing the hub assembly to the knuckle. This will likely require a breaker bar and possibly penetrating oil.
8. Remove the Hub Assembly: This is where the specialized wheel bearing removal tool is vital. The tool will allow you to carefully press out the old bearing from the hub. Consult your repair manual or the tool's instructions for the proper procedure.
9. Install the New Bearing: Use the installation portion of your bearing removal/installation tool to press the new bearing into the hub.
10. Reassemble: Carefully reverse the disassembly steps, ensuring everything is correctly aligned and tightened to the proper torque specifications (found in your repair manual). This includes the axle nut, CV joint, rotor, caliper, and wheel.
11. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
12. Test Drive: Take a short test drive to check for any unusual noises or vibrations.
Important Considerations:
* Torque Specifications: Incorrect torque can damage components or lead to failure. Use a torque wrench and follow the specifications in your repair manual precisely.
* Preload: The new wheel bearing may need to be preloaded correctly; your repair manual will detail how to do this.
* Proper Lubrication: Use the correct type and amount of grease for the new bearing.
This is a simplified overview. Always consult a repair manual specific to your 1999 Kia Sportage EX before attempting this repair. Improperly replacing a wheel bearing can have serious consequences. If you're unsure about any step, seek professional help.
