Here's a general outline of the process. Specific steps may vary slightly depending on which wheel bearing (front or rear) you're replacing. Always consult a repair manual specific to your 1999 Chevy Venture for detailed instructions and torque specifications. A Haynes or Chilton manual is a good investment.
Tools You'll Likely Need:
* Jack and jack stands: Essential for safety. NEVER work under a vehicle supported only by a jack.
* Wheel chocks: To prevent the vehicle from rolling.
* Lug wrench: To remove the wheel.
* Socket set and wrenches: Various sizes will be needed.
* Torque wrench: Crucial for tightening bolts to the correct specifications.
* Ball joint separator: May be needed to separate the ball joint from the control arm (front wheel bearing).
* Tie rod separator: May be needed to separate the tie rod from the steering knuckle (front wheel bearing).
* Hammer and punch: Possibly needed for removing parts.
* Wheel bearing press: Highly recommended for safely installing the new bearing. Improper installation can damage the bearing. A socket and hammer might be used in a pinch, but this is risky.
* Penetrating lubricant (PB Blaster or similar): Helps loosen rusted or seized bolts.
* Clean rags or shop towels: To keep things clean.
* New wheel bearing: Make sure you get the correct part number for your Venture.
General Steps (Front Wheel Bearing - More Complex):
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels.
2. Raise and Secure: Safely raise the vehicle using the jack and secure it on jack stands.
3. Remove Wheel: Remove the wheel and tire.
4. Disconnect Brake Caliper: Carefully disconnect the brake caliper and secure it out of the way. You might need to use a zip tie or bungee cord to keep it from hanging by the brake line.
5. Remove Rotor (if applicable): The rotor may need to be removed to access the bearing.
6. Disconnect Ball Joint and Tie Rod: This is often the most challenging part. You'll likely need a ball joint separator and tie rod separator. Use caution and avoid damaging the components.
7. Remove Hub Assembly: Once the ball joint and tie rod are disconnected, the hub assembly (containing the bearing) can be removed. This may require removing some other components.
8. Press Out Old Bearing: Using a wheel bearing press, carefully press out the old bearing. A slide hammer might also work, but a press is safer and more effective.
9. Press In New Bearing: Using the wheel bearing press, carefully press the new bearing into place.
10. Reassemble: Reinstall the hub assembly, reconnect the ball joint and tie rod, reinstall the rotor (if applicable), and reconnect the brake caliper.
11. Torque Specifications: Tighten all bolts to the correct torque specifications as specified in your repair manual.
12. Lower Vehicle: Carefully lower the vehicle and reinstall the wheel.
13. Test Drive: Test drive the vehicle to ensure the repair was successful.
General Steps (Rear Wheel Bearing - Usually Simpler):
The rear wheel bearing replacement is generally less complicated than the front, as it doesn't involve disconnecting ball joints and tie rods. However, you'll still need to follow the steps above for safety and disassembly. The specific steps for removing the hub assembly and bearing will differ. Refer to your repair manual.
Important Considerations:
* ABS Sensors: Be careful not to damage the ABS sensor (if equipped) during the process.
* Torque Specifications: Use a torque wrench and follow the manufacturer's specifications religiously. Incorrect torque can damage components.
* Hub Nut: The hub nut is usually very tight. You may need an impact wrench or breaker bar.
* Professional Help: If you're not comfortable with any of these steps, take your vehicle to a qualified mechanic. A botched wheel bearing repair can lead to dangerous consequences.
This is a simplified overview. Always consult a repair manual specific to your 1999 Chevy Venture for detailed instructions and torque specifications. Failure to do so could result in damage to your vehicle or personal injury.
