Suspension Knuckle
A suspension knuckle or a steering knuckle is a connecting point where the upper and lower suspension parts meet together. It also provides support for the wheel hub that, in turn, is used to secure the wheel. It is also connected to a tie rod, which pushes or pulls the knuckle, turning the wheel into a desired direction.
A failing suspension knuckle can cause excessive or uneven tire wear, and keep the brake caliper bracket from securing properly.
Suspension knuckle replacement and troubleshooting
- A four-wheel alignment is recommended when replacing a steering knuckle. Being a part of your steering system, it can affect your vehicle’s alignment settings.
- If the threads in the knuckle that are used to secure a brake caliper bracket are worn out or damaged, you will need to replace the knuckle as it is not repairable.
