Replacement and Maintenance
Steering knuckles are not serviceable parts – they are designed to last the life of the vehicle under normal conditions. Replacement is typically needed only if the knuckle is damaged (e.g. from a collision) or if it has worn beyond acceptable tolerances (which is rare unless there’s a manufacturing defect or extreme wear). Here are important considerations regarding replacement and maintenance:

When to Replace: You would replace a steering knuckle if it is bent, cracked, or the mounting surfaces are damaged. Signs of a damaged knuckle can include abnormal tire wear, steering wheel vibration, or alignment that cannot be corrected. In the event of a front-end accident, the knuckle should be inspected for damage; even a small bend can affect wheel alignment and handling. Any damage should be addressed promptly with a genuine replacement to maintain the vehicle’s handling precision.



Installation: Replacing a steering knuckle is a complex job requiring proper tools and alignment. The process generally involves:
*Lifting the vehicle and removing the front wheel.
*Disconnecting the tie rod end from the knuckle (often by pressing or using a pickle fork).
*Separating the control arms from the knuckle (this may involve removing ball joints or bushings; on some designs the lower ball joint might be pressed into the knuckle).
*Removing the strut/shock from the knuckle (if it’s mounted to the knuckle).
*Taking out the wheel hub/bearing assembly (if it’s not integrated with the knuckle).
*Unbolting the knuckle from the suspension (the knuckle is typically attached via bolts to the upper and lower control arms and sometimes the strut).

*Installing the new knuckle and reversing the steps. After installation, a professional wheel alignment is mandatory, as the knuckle’s position directly affects wheel angles (camber, caster, toe). Proper alignment ensures even tire wear and correct steering behavior.
