Description
Product Overview
The Crown Automotive Headlight Adjusting Nut is engineered to deliver precise control over headlamp positioning, a critical factor for safe nighttime driving and optimal illumination. Crafted from high‑grade machined steel, the nut provides exceptional strength while maintaining a lightweight profile of just 0.16 ounces. Its compact dimensions—6 × 6 × 5.5 inches—allow it to fit seamlessly into the confined spaces of Jeep headlamp assemblies. The part carries the OEM number 4762490, ensuring an exact match for original equipment specifications and eliminating the guesswork often associated with aftermarket components. Crown’s reputation for quality across a broad range of automotive systems—axle, brake, suspension, and more—extends to this adjusting nut, offering the same rigorous testing and material standards that have earned the brand trust among mechanics and DIY enthusiasts alike.
Usage
Installation of the adjusting nut is straightforward for anyone with basic hand‑tool experience. It is ideal for Jeep owners who regularly navigate off‑road terrain where headlamp alignment can shift due to vibration and impact. The nut’s machined threads engage smoothly with the existing headlamp housing, allowing for fine‑tuned adjustments without stripping or slippage. Whether you are restoring a classic Jeep, performing routine maintenance, or upgrading your lighting system for better visibility, this nut provides a reliable solution. It also serves fleet operators and service shops that require dependable, repeatable results across multiple vehicles.

FAQ

The nut is designed for Jeep vehicles that use the OEM part number 4762490. It fits most models equipped with the standard headlamp adjustment system, but we recommend verifying the part number in your vehicle’s service manual.

No special tools are required. A standard socket or wrench that matches the nut’s size will allow you to tighten and adjust it easily. The machined threads ensure a smooth fit without the need for thread‑locking compounds.

Yes. The nut’s universal design for the specified OEM number makes it suitable for both stock and aftermarket headlamp assemblies, provided the mounting points remain unchanged.

The steel is CNC‑machined from a high‑grade alloy that offers superior tensile strength and resistance to rust and corrosion. This ensures the nut maintains its structural integrity even in extreme temperature fluctuations and exposure to road salts.
