Description
The Toyota Mark X and Toyota Crown Rear Knuckle Hub Assembly is a critical suspension and wheel support component that connects the rear wheel hub to the suspension system while allowing smooth wheel rotation and stable vehicle handling. Built to OEM standards, this assembly ensures proper alignment, strength, and durability under daily driving and load conditions.
This rear knuckle hub assembly is commonly compatible with:
- Toyota Mark X GRX120 / GRX130

The assembly combines the rear knuckle (upright) and wheel hub bearing unit, forming the mounting point for the rear wheel, brake disc, and suspension arms. It plays a key role in maintaining wheel stability, alignment, and safe road contact.
According to automotive suspension design, the steering/knuckle unit (upright) holds the wheel hub and connects to suspension arms, allowing controlled wheel movement while maintaining structural support. (en.wikipedia.org)
