Dorman 686-312 Steering Knuckle - Front Right

Dorman 686-312 Steering Knuckle

Dorman 686-312 is a front right steering knuckle for select Volkswagen SUVs, including the Atlas and Atlas Cross Sport. It addresses a common corrosion issue where the wheel hub bearing can seize to the steering knuckle over time, especially in salt-belt conditions.

Built as an OE FIX replacement, this cast iron knuckle uses a proprietary corrosion-resistant coating on the mating surfaces to help reduce rust buildup and support a more durable repair. For Volkswagen Atlas and Volkswagen Atlas Cross Sport front right applications, it provides a direct replacement path when the original knuckle is no longer serviceable.
