However, if you're determined to do it yourself, here's a general outline. This is not a complete, step-by-step guide and variations may exist depending on your specific Blazer's configuration. Always consult a repair manual specific to your 1997 Chevrolet Blazer 2WD 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 secure the other wheels.
* Lug wrench: To remove the wheel.
* Socket set and wrenches: Various sizes will be needed.
* Hammer and punch: For removing and installing components.
* Pry bar: Might be needed to separate parts.
* Torque wrench: Crucial for tightening bolts to the correct specification. Incorrect torque can damage components.
* Grease gun: To pack the new bearing with grease.
* Penetrating oil (like PB Blaster): To help loosen rusted bolts.
* Wheel bearing press (highly recommended): Makes the job significantly easier and reduces the risk of damaging the new bearing. Improvising can damage the bearing or axle.
* New wheel bearing: Ensure you get the correct part number for your specific Blazer.
* Safety glasses and gloves: Protect yourself from injury.
General Steps (Simplified – Consult a repair manual for specifics):
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels.
2. Remove the Wheel: Loosen the lug nuts before jacking up the vehicle. Jack up the vehicle securely and place it on jack stands. Remove the wheel.
3. Remove the Brake Caliper and Rotor: Carefully remove the brake caliper (support it to prevent strain on the brake line) and rotor.
4. Remove the Hub Assembly: This often involves removing cotter pins, nuts, and possibly a retaining ring. The hub assembly will likely be attached to the bearing.
5. Remove the Old Bearing: This is where the wheel bearing press is invaluable. Trying to remove the bearing without one is extremely difficult and risky.
6. Clean and Inspect: Thoroughly clean the hub and axle. Inspect for any damage.
7. Install the New Bearing: Use the press to carefully install the new bearing, ensuring it's seated properly.
8. Reassemble: Carefully reinstall the hub assembly, rotor, caliper, and wheel, ensuring everything is properly aligned and tightened to the correct torque specifications (consult your repair manual).
9. Pack with Grease: Apply grease to the bearing as specified in your repair manual.
10. Test: Lower the vehicle and carefully test drive the vehicle at low speeds to verify the repair.
Important Considerations:
* ABS Sensors: If your Blazer has anti-lock brakes (ABS), be careful with the ABS sensor. It's usually located near the wheel bearing.
* Torque Specifications: Using the correct torque is paramount to prevent damage.
* Parts: Buy quality parts from a reputable source.
This is a simplified overview. Always consult a detailed repair manual for your specific vehicle before attempting this repair. If you are not comfortable with the task, taking your Blazer to a mechanic is the safest and likely most cost-effective option in the long run. A poorly done wheel bearing replacement can lead to serious accidents.
