Key Features:

• Contains the wheel hub assembly and attaches to both suspension and steering components
• Replaces part numbers 5168421AC, 5168421AD, and 5168421AE

The steering knuckle serves as a rigid foundation point in the steering and suspension system, maintaining proper steering geometry angles while allowing the wheel to articulate up and down and pivot left and right. Knuckles can be damaged during collisions, from striking curbs or deep potholes, which can change suspension geometry and cause steering issues, crooked steering wheel alignment, or abnormal tire wear. Replacing a damaged knuckle with this genuine Mopar part restores factory specifications and ensures safe, reliable steering performance.
