Here's a general outline of the process. Always consult a repair manual specific to your 2003 Pontiac Rendezvous for detailed instructions and torque specifications. Improper torque can damage components.
Tools You'll Likely Need:
* Jack and jack stands: Crucial for safety. Never work under a vehicle supported only by a jack.
* Wheel chocks: To secure the other wheels.
* Lug wrench: To remove the wheel.
* Socket set and wrenches: Various sizes will be needed.
* Torque wrench: Essential for proper tightening.
* Ball joint separator: May be needed to separate the control arm from the steering knuckle.
* Hammer and punch: Possibly needed for stubborn parts.
* Penetrating oil (PB Blaster or similar): Helps loosen rusted or seized bolts.
* Wheel bearing press (or suitable substitute): This is often the most critical tool. Improper removal/installation can damage the new bearing. A shop press is ideal but some DIY solutions exist (though riskier).
* New wheel bearing assembly: Get the correct part number for your vehicle. Don't try to just replace the bearing itself within the assembly.
General Steps (Consult your repair manual for specifics):
1. Safety First: Engage the parking brake, chock the wheels, and wear safety glasses.
2. Raise and Secure: Safely raise the vehicle using the jack and secure it on jack stands.
3. Remove the Wheel: Remove the lug nuts and take off the wheel.
4. Disconnect Brake Caliper: Carefully remove the brake caliper and hang it securely out of the way using a wire or bungee cord. Do NOT let the brake hose hang freely.
5. Disconnect ABS Sensor (if applicable): Carefully unplug the ABS sensor wire from the hub.
6. Disconnect Sway Bar Link: Disconnect the sway bar link from the control arm.
7. Remove the Axle Nut: This nut is usually very tight. Use a breaker bar or impact wrench if necessary.
8. Separate Ball Joint: Use a ball joint separator to separate the lower ball joint from the steering knuckle.
9. Remove the Hub Assembly: This step often requires careful prying and tapping. The hub assembly is likely pressed onto the spindle.
10. Press Out Old Bearing: Use a wheel bearing press to carefully remove the old bearing assembly from the hub. This is a critical step; damaging the hub will necessitate a more costly repair.
11. Press In New Bearing: Use the press to install the new hub assembly.
12. Reassembly: Reassemble everything in the reverse order of disassembly, paying close attention to torque specifications for all bolts and nuts. Make sure the ABS sensor is properly connected and that the brake caliper is correctly positioned.
13. Lower Vehicle: Carefully lower the vehicle.
14. Torque Specifications: Double-check all torque specifications in your repair manual.
15. Test Drive: After reassembly, test drive the vehicle to ensure the repair was successful. Listen for any unusual noises.
Important Considerations:
* Hub Assembly vs. Individual Bearing: It's almost always more practical and reliable to replace the entire hub assembly instead of trying to press out and replace just the bearing itself. The cost difference is usually minimal.
* Pressing the Bearing: Using the correct press is paramount to avoid damaging the new bearing or the hub. Improper installation can lead to premature bearing failure.
* Repair Manual: A repair manual specific to your 2003 Pontiac Rendezvous is indispensable. It will provide detailed diagrams, torque specifications, and crucial step-by-step instructions.
Again, this is a complex job. If you are not comfortable with this level of car repair, take your vehicle to a qualified mechanic. Improper repair can lead to serious safety issues.
