Here's a general procedure. Variations may exist depending on your specific Blazer's configuration. Always consult a repair manual specific to your year and model for the most accurate instructions and torque specifications.
Tools You'll Need:
* Jack and jack stands: Essential for safely lifting the vehicle.
* Lug wrench: To remove the wheel.
* Wheel chocks: To prevent the vehicle from rolling.
* Socket wrench and sockets: Appropriate size for the lug nuts and the wheel stud nut (likely 1/2" drive).
* Hammer and punch (or a slide hammer): To drive out the old stud.
* New wheel stud: Get the correct replacement from a parts store; specifying your year and model is crucial.
* Torque wrench: Absolutely necessary to tighten the new stud and lug nuts to the correct specifications.
* Penetrating oil (like PB Blaster): May help loosen stubborn parts.
* Safety glasses: Protect your eyes from flying debris.
* Gloves: Protect your hands.
Procedure:
1. Safety First: Park on a level surface, engage the parking brake, and chock the rear wheels. Use jack stands to securely lift the front of the vehicle. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the lug nuts and carefully remove the wheel.
3. Access the Stud: You should now have clear access to the wheel studs. The damaged stud will be sticking out from the hub.
4. Remove the Old Stud: This is often the trickiest part. Apply penetrating oil to the stud if necessary, allowing it to soak in. Use a punch and hammer (or a slide hammer – much easier!) to carefully drive the old stud out from the back of the hub. Work slowly and avoid damaging the hub. Sometimes a socket that fits snugly on the end of the stud can be used to help drive it out.
5. Install the New Stud: Carefully insert the new stud into the hub from the back side. Make sure it's seated fully and straight. Use a nut on the new stud to secure it and prevent it from falling back through. Tighten this nut firmly, but don't overtighten it yet.
6. Tighten the Nut: Use the torque wrench to tighten the nut on the new stud to the manufacturer's specified torque. This is crucial to prevent the stud from backing out or failing. This torque value will be in your repair manual.
7. Reinstall the Wheel: Carefully reinstall the wheel and tighten the lug nuts in a star pattern (opposite nuts first, then the ones in between). Again, use your torque wrench to tighten them to the manufacturer's specified torque. This is *also* crucial for safety.
8. Lower the Vehicle: Slowly lower the vehicle and remove the jack stands. Double-check the lug nuts for tightness.
9. Test Drive: After you've finished, carefully test drive the vehicle to verify everything is working correctly.
Important Considerations:
* Hub Damage: If the hub is damaged during stud removal, you may need to replace the entire hub assembly.
* Torque Specifications: Following the correct torque specifications is crucial for the safety and longevity of your vehicle's components. Refer to your repair manual.
* Professional Help: If you're not comfortable performing this repair yourself, it's always best to take your vehicle to a qualified mechanic.
This is a general guide. Consult a repair manual specific to your 1992 Chevy S10 Blazer for detailed instructions and torque specifications. Remember safety first!
