How does the steering knuckle work?

The steering knuckle houses the wheel hub (the wheel is connected to the hub with the lug nuts or bolts) and wheel bearing. On some vehicles, the hub is bolted to the steering knuckle; on others, it is pressed into the knuckle. Attached at the top and bottom of the steering knuckle, by way of the ball joints, are the control arms that allow the suspension to travel up and down. The steering knuckle is turned by the steering system, and it connects through an arm called a tie rod.

What are the symptoms related to a bad steering knuckle?

The steering knuckle itself does not often fail. It is possible for the knuckle to become damaged if the vehicle is in a crash, or if it encounters a large pothole. It is more likely that the components in and around the steering knuckle - ball joints, bearings, control arm bushings, tie rod ends - are worn. If indeed the steering knuckle is damaged, symptoms might include tires that are excessively worn on the inside and outside edges or the vehicle pulls to one side when driving. A damaged steering knuckle might present during a suspension alignment. The threads with which the brake caliper is connected to the steering knuckle may become damaged at some point during brake system service. If the threads are damaged, the knuckle should be replaced.

Can I drive with a steering knuckle problem?

Whether or not a vehicle can be driven with issues related to the steering knuckle is dependent upon the specific component that is worn or failing (see individual components for more information: wheel hub, wheel bearing, control arm, tie rod end). The steering knuckle is not often a problem unless it has been damaged. If the threads to which the brake caliper is attached are damaged and the caliper cannot be secured (during brake service), the vehicle should not be driven until the steering knuckle has been replaced.
