Quick facts
- Part: Dorman 686-451 steering knuckle
- Fits: 2016-2018 Kia Sorento
- Position: Front left
- Material: Cast iron
- Condition: New
A knuckle that is cracked or bent, or that has seized to the hub bearing, needs replacing. Steering looseness or a noise from the front left wheel can come from the knuckle, but these signs alone do not prove it is at fault; a worn wheel bearing is another common cause. This listing is one knuckle for the front left. The front axle takes one on each side, the front right is a separate part, and both sides are normally replaced together.
Fits
It is a direct replacement for the 2016-2018 Kia Sorento, engineered to perform like the original equipment steering knuckle.
