The Problem
Premature slider (or telescoping) ball joint failures are a common occurrence on many late model Dodge and RAM trucks and Jeep SUVs equipped with a 9.25" axle. The OE ball joints are not greaseable, which can increase the rate at which they wear. As the ball joint wears, looseness develops in the socket. Vertical movement of the stud is normal, but once radial movement (side-to-side or back-and-forth play) exceeds manufacturer specifications, it’s time to replace the ball joint.
When upper slider ball joint replacement is necessary, the installation procedure puts significant stress on the upper ball joint housing, as the upper and lower ball joints may not align perfectly. The OE upper ball joint design deforms to compensate for this misalignment, which leads to severe wear from impact loads that occur throughout normal driving conditions.
The Solution
A proven solution to this problem, the MOOG® Problem Solver upper slider ball joint design improves durability and minimizes radial play. It has a patented all-metal bowl design that compensates for suspension component misalignment through a unique rotational pivot (stud swinging movement), and a patented closure method that minimizes radial deflection. In addition, they use a premium neoprene boot with a built-in grease-relief valve, providing a sealed, serviceable part able to flush contamination.
- Greaseable design makes lubrication service easier, contributing to longer component life.
- Patented pressed-in cover plate virtually eliminates excess axial and radial movement to deliver solid steering feel for the life of the part.
- Gusher bearing and pressure cup stands up to impact.
- Spherical bearing for smooth rotation and articulation.
