1. Safety First:
* Jack up the truck securely: Use jack stands, *never* rely solely on the jack. Chock the wheels.
* Safety glasses and gloves: Protect yourself from flying debris and potential injuries.
2. Removing the Broken Stud:
This is the trickiest part and depends on how the stud broke:
* Stud snapped off flush with the hub: This is the hardest. You'll likely need a stud remover tool. These tools are usually a threaded bolt that screws into the remaining broken stud and allows you to extract it. You might need a few different sizes to find one that fits. If it's really stubborn, you might need to use heat (carefully!) to expand the metal. *Be extremely cautious not to damage the hub*.
* Stud broke off leaving a portion sticking out: Use vise grips or pliers to grip and twist the broken piece out. Be careful not to damage the surrounding threads.
3. Installing the New Stud:
* Clean the threads: Ensure the threads in the hub are clean and free of debris. A tap and die set (the correct size for your wheel studs) might be helpful to clean up any damaged threads.
* Lubricate the new stud: Use a little anti-seize compound on the threads of the new stud to help with installation and future removal.
* Install the new stud: Carefully screw the new stud into the hub using your fingers or a socket, until it's fully seated. Don't force it; if it's not going in easily, something's wrong.
* Torque to specifications: Use a torque wrench to tighten the new stud to the manufacturer's specification. This is crucial to prevent future problems. Consult your truck's repair manual for the correct torque value.
4. Reassemble:
* Install the wheel and lug nuts. Torque the lug nuts to the proper specification as well.
Important Considerations:
* Hub Condition: Carefully inspect the wheel hub for any damage during the stud removal process. Any significant damage to the hub may require hub replacement.
* Wheel Stud Size: Make absolutely sure you get the correct size and length wheel studs for your 1984 Chevrolet Silverado. Incorrectly sized studs can be dangerous. A parts store can help you identify the correct ones by your vehicle's VIN or hub details.
* Repair Manual: A factory service manual for your 1984 Chevrolet Silverado is highly recommended. It will provide detailed information about torque specifications, stud size, and other important details.
If you are not comfortable performing this repair, take your truck to a qualified mechanic. Improperly installed wheel studs can lead to wheel failure and serious accidents. It's better to be safe than sorry.
