Safety Information

Always prioritize safety when working on vehicles. Failure to follow proper safety procedures can result in serious injury or damage to the vehicle.

• Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
• Ensure the vehicle is securely supported on jack stands on a level surface before removing wheels or working underneath. Never rely solely on a jack.
• Use the correct tools for the job.
• Consult your vehicle's service manual for specific torque specifications and procedures.
• Keep children and pets away from the work area.

Installation Instructions

These instructions provide a general guide for replacing wheel studs. Specific procedures may vary by vehicle make and model. Always refer to your vehicle's service manual for detailed instructions.

1. Prepare the Vehicle: Park the vehicle on a level surface, engage the parking brake, and block the wheels that will remain on the ground. Loosen the lug nuts on the wheel requiring stud replacement while the wheel is still on the ground.
2. Lift and Secure: Safely lift the vehicle using a jack and secure it with jack stands. Remove the lug nuts and the wheel.
3. Access the Hub: Depending on the vehicle, you may need to remove the brake caliper, rotor, or other components to gain access to the wheel hub and the back of the stud.
4. Remove Old Stud: Use a hammer to carefully tap out the old, damaged wheel stud from the back of the hub. Ensure the hub is supported to prevent damage.
5. Install New Stud: Insert the new Dorman serrated wheel stud through the hole from the back of the hub. Ensure the knurled section aligns correctly with the hole.
6. Seat the Stud: Place a flat washer and a spare lug nut (or a specialized stud installer tool) onto the new stud. Tighten the lug nut until the stud is fully seated and flush against the back of the hub. Do not overtighten. Remove the lug nut and washer.
7. Reassemble: Reinstall any removed brake components, the wheel, and lug nuts.
8. Lower Vehicle and Torque: Lower the vehicle until the wheel just touches the ground. Torque the lug nuts to the vehicle manufacturer's specified torque settings in a star pattern.
9. Final Check: Fully lower the vehicle and remove jack stands. Double-check all lug nuts for proper torque after driving a short distance (e.g., 50-100 miles).

Maintenance and Inspection

Regular inspection of your wheel studs is vital for vehicle safety.

• Visual Inspection: Periodically inspect wheel studs for signs of damage, corrosion, bending, or stripped threads. This should be done whenever wheels are removed for tire rotation or brake service.
• Lug Nut Engagement: Ensure lug nuts thread smoothly onto the studs and engage fully. If a lug nut feels loose or difficult to thread, inspect the stud for damage.
• Torque Check: Re-torque lug nuts after any wheel service or after driving a short distance following new stud installation.
• Replacement: Replace any wheel stud that shows signs of damage, wear, or corrosion immediately. Do not attempt to repair damaged studs.

Troubleshooting Common Issues

• Problem: Lug nut will not thread onto the stud.
  Solution: Inspect the stud threads for damage or cross-threading. If threads are damaged, the stud must be replaced. Do not force the lug nut.
• Problem: Wheel stud spins when attempting to remove or install a lug nut.
  Solution: This indicates the stud's knurl is no longer properly seated in the hub. The stud must be replaced.
• Problem: Visible corrosion or rust on the stud.
  Solution: While Dorman studs are corrosion tested, severe corrosion can compromise strength. Replace severely corroded studs.
• Problem: Stud appears bent or cracked.
  Solution: Immediately replace any bent or cracked wheel stud. This is a critical safety concern.
