Wheel Studs with Yellow Coating

The new 2019 Silverado and Sierra use wheels studs that have a yellow coating on the lower portion of the stud threads to prevent corrosion of the threads. (Fig. 14) The yellow coating is not Loctite or any type of anti-seize coating for the wheel studs.

TIP: Never apply Loctite or any other product to any wheel stud threads. Never grease or lubricate the wheel nuts, studs or mounting surfaces. Wheel nuts, studs and mounting surfaces must be clean and dry.

The yellow coating is designed to prevent corrosion on the portion of the thread that is not covered by the wheel nut. (Fig. 15) The coating should not be removed or supplemented with any other product. If the coating comes off the wheel stud, it is not necessary to replace the stud.

Always clean the threads of the wheel studs before installing the tire and wheel assembly. If the threads of the wheel stud are damaged, replace the wheel stud.

The 2019 Silverado and Sierra are the first models/model year to receive the coating on the wheel studs. The coating will be applied on additional models in future model years.
