Removing the Damaged Lug Nuts
Damaged lug nuts can be a frustrating obstacle when attempting to replace a stud on a wheel. Here’s a detailed guide to safely remove damaged lug nuts:
Assess the Damage:
Determine the extent of the damage to the lug nut. Surface scratches or mild corrosion can be removed with a wire brush or penetrating oil. However, if the damage is significant, such as stripped threads or broken bolts, removal will require specialized tools.
Select the Appropriate Tool:
The type of tool you need will depend on the severity of the damage. For superficial damage, a regular socket wrench will suffice. For more severe damage, you may need to use a bolt extractor or an impact wrench.
Apply Penetrating Oil:
Before attempting to loosen the lug nut, apply a generous amount of penetrating oil to the threads and allow it to soak in for several minutes. This will help break down any rust or corrosion and make removal easier.
Use a Bolt Extractor (if necessary):
If the lug nut is severely damaged or stripped, a bolt extractor is required. These extractors grip onto the damaged bolt and allow you to turn it out. Choose the appropriate extractor size for the lug nut diameter and thread pitch.
Use an Impact Wrench (if necessary):
For stubborn lug nuts that resist removal, an impact wrench can provide the necessary force. Apply short, sharp bursts of power to break the nut loose, taking care not to apply excessive force that could damage the wheel or stud.
Wrap the Stud in a Rag:
To prevent the stud from being scratched or damaged during removal, wrap it in a rag. This will cushion the stud and prevent it from contacting the tools.
Twist and Turn the Lug Nut:
Using the appropriate tool, apply gentle pressure and twist the lug nut back and forth. Gradually increase the force until the nut loosens and can be completely removed.
Inserting the New Stud
1. Confirm the stud’s fit. Slide the new stud into the hole in the wheelbase to ensure a snug fit without any wobbling.
2. Apply Loctite. Apply a small amount of Loctite or other thread adhesive to the base of the stud to prevent it from loosening over time.
3. Slowly tighten the stud. Using a socket wrench, gently and gradually tighten the stud into the hole, taking care not to overtighten it.
4. Alternate tightening. To ensure even tightening, tighten multiple studs partially, then go back and fully tighten each one at a time.
5. Use a torque wrench (optional). If you have access to a torque wrench, follow the recommended torque specification for the specific make and model of your vehicle. This ensures the stud is tightened to the correct tension.
6. Double-check tightness. Use a torque wrench or socket wrench to re-check the tightness of each stud, ensuring they are all securely fastened.
Tightening the Stud
Follow these steps to properly tighten the stud:
1. **Position the wheel:** Place the wheel onto the hub, ensuring it is aligned correctly.
2. **Thread the stud:** Manually thread the stud into the hub until it is hand-tight.
3. **Use a wrench:** Use a torque wrench to tighten the stud to the specified torque. Refer to the vehicle’s manufacturer’s specifications for the exact torque value.
4. **Tighten evenly:** Alternately tighten the studs on opposite sides of the wheel to distribute the force evenly and prevent warping.
5. **Double-check:** Recheck the stud tightness with the torque wrench to ensure they are all torqued to the correct specification.
6. **Additional considerations:**
a. **Lubrication:** Apply a light coating of anti-seize lubricant to the threads of the stud to prevent corrosion and ensure proper tightening.
b. **Thread quality:** Inspect the stud threads for damage or wear. Replace the stud if there are any irregularities.
c. **Loose stud:** If a stud is loose after tightening, remove it and inspect the hub. There may be an underlying issue that needs to be addressed.

| 80-90 ft-lbs | Passenger cars |
| 100-120 ft-lbs | Light trucks |
| 130-150 ft-lbs | Heavy-duty trucks |
Installing New Lug Nuts
To install new lug nuts, start by cleaning the threads of the lug bolts and the lug nuts themselves. This will help ensure a secure fit. Next, apply a small amount of anti-seize compound to the threads of the lug bolts. This will help prevent the lug nuts from seizing and make it easier to remove them in the future.
Now, thread the lug nuts onto the lug bolts by hand. Tighten the lug nuts as much as possible by hand, then use a torque wrench to tighten them to the specified torque. The torque specification can be found in your vehicle’s owner’s manual.
Once the lug nuts are tightened, use a lug wrench to tighten them further. Be sure to tighten the lug nuts in a star pattern, this will help ensure that the wheel is evenly tightened. Once the lug nuts are tightened, double-check the torque to make sure they are tight enough.
Finally, install the wheel cover or hubcap. If your vehicle has a locking lug nut, be sure to tighten it last and use the key that came with the lug nut to tighten it.
