Tools You'll Likely Need:
* Jack and jack stands: Essential for safe vehicle lifting.
* Wheel chocks: To prevent the vehicle from rolling.
* Lug wrench: To remove the wheel.
* Torque wrench: Crucial for tightening bolts to the correct specifications.
* Hammer and punch: Possibly needed to remove components.
* Socket set and wrenches: Various sizes will be needed.
* Pry bar: May be helpful for separating components.
* New rear wheel bearing assembly: Get the correct part number for your vehicle.
* Penetrating oil (like PB Blaster): To help loosen rusted or seized parts.
* Grease: For lubricating the new bearing.
* Repair manual specific to your 2000 Pontiac Montana: This is indispensable.
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. Wear safety glasses.
2. Lift and Secure: Safely lift the vehicle using a jack and secure it on jack stands. Never work under a vehicle supported only by a jack.
3. Remove Wheel: Remove the lug nuts and take off the wheel.
4. Remove Brake Components: This typically involves removing the caliper (supporting it with wire to avoid stretching the brake line), brake rotor, and possibly the parking brake components. Your repair manual will show the precise order and method. Take pictures as you go to aid reassembly.
5. Remove Axle Nut and Hub: This step is crucial and often requires significant torque to remove the axle nut. You might need a breaker bar or impact wrench. Once the nut is off, the hub assembly should be removable.
6. Remove the Old Bearing: The old bearing is usually pressed onto the hub. Removal might require a bearing puller, but sometimes a hammer and punch (used carefully) can work. Be extremely cautious not to damage the axle.
7. Install New Bearing: Press the new bearing onto the hub. Again, a bearing press is ideal, but sometimes gentle tapping with a socket and hammer (using a large surface area to distribute force) can work if done carefully.
8. Reassembly: Carefully reassemble everything in the reverse order of disassembly, referring constantly to your repair manual. Pay close attention to the torque specifications for all bolts and nuts. Apply grease to the new bearing as specified by the manufacturer.
9. Test Drive: After reassembly, take a short test drive to check for any unusual noises or vibrations.
Important Considerations:
* Axle Nut Torque: Incorrect torque on the axle nut can lead to serious damage. Follow your repair manual's specifications precisely.
* Bearing Press: Using a bearing press is highly recommended for both removal and installation to prevent damage.
* ABS Sensors: If your vehicle has Anti-lock Braking System (ABS), be mindful of the ABS sensor during disassembly and reassembly.
* Professional Help: If you're not comfortable with this level of auto repair, take your vehicle to a qualified mechanic. Improperly replacing a wheel bearing can lead to catastrophic failure.
This is a simplified overview. Always consult your repair manual for detailed instructions specific to your 2000 Pontiac Montana. Improper repair could lead to damage to your vehicle or serious injury.
