This is a general overview and may not cover all variations. Always refer to your repair manual.
Tools You Will Likely Need:
* Jack and jack stands: Essential for safely lifting the vehicle.
* Wheel chocks: For safety.
* Lug wrench: To remove the wheel.
* Socket set and wrenches: Various sizes will be needed.
* Hammer and punch: Possibly to remove components.
* Bearing puller: Specific pullers are often needed to remove the bearing from the hub. A slide hammer may also be helpful.
* Bearing race installer: To install the new bearing races (inner and outer).
* Torque wrench: Absolutely crucial for tightening components to the correct specification.
* Penetrating oil (PB Blaster, etc.): To help loosen rusted or seized parts.
* Clean rags: To keep things clean and prevent contamination.
* New rear wheel bearings and races (inner and outer): Ensure you get the correct parts for your specific Venture model.
* Grease: High-quality wheel bearing grease.
General Steps (Consult your repair manual for specifics!):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks. Raise the vehicle using the jack and securely support it with jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Brake Caliper and Rotor: Carefully remove the brake caliper (usually requires unbolting it and hanging it out of the way with wire or a bungee cord), then remove the rotor.
4. Remove the Axle Nut: This is often a very large nut and may require a breaker bar or impact wrench. Mark the nut's position relative to the axle flange before removing it, to ensure proper reinstallation.
5. Remove the Hub Assembly: This may require separating the hub from the axle flange. This is where a bearing puller is usually necessary. The process will vary depending on your Venture's design. Some models require removing the ABS sensor, etc.
6. Remove the Old Bearings and Races: Use the appropriate puller to remove the old bearings and races from the hub assembly.
7. Clean and Inspect: Clean the hub assembly thoroughly, inspecting it for any damage.
8. Install the New Bearings and Races: Using the bearing race installer, carefully install the new inner and outer races. Then carefully press the new bearing onto the hub assembly (often requires a press or specialized tool).
9. Reassemble: Reinstall the hub assembly, axle nut (tightening to the specified torque), rotor, and brake caliper. Proper torque is critical to prevent damage and ensure proper function.
10. Bleed the Brakes (if necessary): After reconnecting the brake caliper, you may need to bleed the brakes to remove any air that may have entered the system.
11. Lower the Vehicle: Carefully lower the vehicle and reinstall the wheel. Torque the lug nuts to the proper specification.
Important Considerations:
* ABS Sensors: If your Venture has Anti-lock Braking System (ABS), you will likely need to disconnect and reconnect the ABS sensor during the process. Be careful not to damage it.
* Torque Specifications: Using a torque wrench and adhering to the manufacturer's torque specifications for all bolts and nuts is absolutely crucial. Incorrect torque can lead to premature failure and safety hazards.
* Professional Help: If you are not comfortable performing this repair yourself, take it to a qualified mechanic. Improperly installed wheel bearings can lead to serious consequences.
This is a simplified overview. Always consult a repair manual specific to your 2004 Chevy Venture before attempting this repair. This information is for informational purposes only and does not constitute professional automotive advice.
