Detailed Description

This Dorman suspension ball joint is designed for front lower use on 2009-2010 Dodge Ram 1500, front lower; 2011-2018 Ram 1500, front lower; and 2019-2024 Ram 1500 Classic, front lower. It is a steel, press-in replacement with a tapered stud and polychloroprene dust boot, made to match the service requirements of the original suspension layout.

This part cross-references MOOG Chassis Products (e.g., K500286, K500286T005) for the same application.

Common Problems This Part Can Help Address

• Front-end clunking or popping from a worn lower ball joint
• Excessive suspension play or looseness in the front end
• Uneven tire wear caused by worn steering and suspension joints
• Steering wander or reduced directional stability
• Boot damage that exposes the joint to dirt and moisture

Installation Notes and Tips

Installation requires press-in service on the front lower suspension position. Inspect the control arm, surrounding hardware, and mating surfaces before installation, and verify the tapered stud and 16 mm wrench size match the vehicle service procedure. Because this is a non-greaseable design, routine lubrication is not part of service maintenance.

Quality Assurance

Dorman states that this ball joint is precision-engineered and rigorously tested to serve as a reliable replacement for the original equipment on the listed vehicles. The part is built to standard suspension replacement specifications for consistent service fitment.
