Installation (Setup)

Proper installation of wheel lug studs is critical for vehicle safety. If you are unsure about any step, consult a qualified automotive technician.

Required Tools:

• Lug wrench or impact gun
• Torque wrench
• Jack and jack stands
• Wheel chocks
• Wire brush (for cleaning hub)
• Anti-seize lubricant (optional, for threads)

Installation Steps:

1. Prepare the Vehicle: Park the vehicle on a flat, level surface. Engage the parking brake and place wheel chocks on the wheels that will remain on the ground. Loosen the lug nuts on the wheel you intend to work on while the vehicle is still on the ground.
2. Lift the Vehicle: Using a jack, lift the vehicle until the wheel is off the ground. Secure the vehicle with jack stands for safety. Remove the lug nuts and the wheel.
3. Remove Old Studs (if applicable): If replacing existing studs, use a hammer to carefully tap out the old studs from the rear of the hub. Ensure the hub surface is clean and free of rust or debris using a wire brush.
4. Install New Studs: Insert the new SANWA lug stud through the back of the hub assembly. Ensure the knurled portion of the stud is fully seated into the hub. You may need to use a lug nut and washers, or a specialized stud installer tool, to pull the stud through until it is flush and tight against the hub. Do not use an impact gun for this step as it can damage the stud or hub.
5. Reinstall Wheel: Place the wheel back onto the hub, aligning the holes with the newly installed studs. Hand-tighten the lug nuts onto the studs.
6. Lower Vehicle and Torque: Lower the vehicle until the wheel just touches the ground, but the full weight is not on it. Using a torque wrench, tighten the lug nuts in a star pattern to the vehicle manufacturer's specified torque settings. Refer to your vehicle's owner's manual for correct torque values.
7. Final Check: Fully lower the vehicle and remove the jack and jack stands. Double-check all lug nuts with the torque wrench to ensure they are properly tightened.

Warning: Incorrect installation can lead to wheel detachment, causing serious injury or death. Always follow manufacturer's torque specifications and consult a professional if unsure.

Operating Considerations

Once installed, the lug studs function as the secure attachment points for your vehicle's wheels. Proper operation involves ensuring the lug nuts remain tightened to specification.

Post-Installation Check:

After driving approximately 50-100 miles following installation or wheel removal, re-check the torque of all lug nuts. This is crucial as new studs or wheels can settle, potentially loosening the nuts. Re-torqueing ensures continued safety.

Regular Checks:

It is recommended to periodically check lug nut torque, especially after significant temperature changes or off-road driving. Loose lug nuts can lead to stud failure or wheel loss.

Maintenance

SANWA lug studs are designed for long-term durability. Regular inspection and proper care will extend their lifespan and ensure safe operation.

Inspection:

• Visual Check: During tire rotations or brake inspections, visually inspect the lug studs for any signs of damage, such as bending, stripping of threads, or corrosion.
• Thread Condition: Ensure the threads are clean and free of debris. If applying anti-seize, use it sparingly and only on the threads, not under the lug nut seat, as this can affect torque readings.
• Knurl Seating: Verify that the knurled portion of the stud remains fully seated in the wheel hub. Any movement indicates improper installation or a damaged hub.

Cleaning:

Keep the studs and lug nut seats clean. Dirt, rust, or foreign material can interfere with proper torque and seating, leading to unsafe conditions.

Replacement:

Replace any lug stud that shows signs of damage, including stripped threads, bending, or significant corrosion. Never attempt to repair a damaged lug stud.
