Dorman 686-312 Replacement Steering Knuckle Assembly

The Dorman 686-312 is a direct-fit replacement steering knuckle designed to restore proper steering geometry and suspension integrity. The steering knuckle — also called a spindle, upright, or wheel knuckle — is a critical chassis component that serves as the pivot point for the front wheel, connecting the wheel hub and bearing assembly to the upper and lower control arms or strut while allowing the wheel to turn for steering.

Dorman engineers this replacement knuckle to match OE specifications for a precise, no-modification-required installation, making it an ideal solution for knuckles damaged by corrosion, impact, or worn mounting points that can no longer be properly repaired.

Key Features:

• Direct OE replacement — engineered to match original equipment specifications
• Restores correct steering geometry, caster, and camber alignment points
• Precision-cast construction for strength and durability
• Pre-drilled mounting points for straightforward installation
• Eliminates the need to source a used or salvage-yard knuckle
• Manufactured by Dorman, a trusted leader in OE-quality replacement parts

Replacing a damaged or compromised steering knuckle is essential for safe vehicle operation. A faulty knuckle can cause improper wheel alignment, uneven tire wear, and unpredictable handling. The Dorman 686-312 provides a reliable, cost-effective alternative to dealer-sourced parts.
