Resolving Upper ball joint failure on dodge/ram trucks

The Problem

Premature ball joint failures are a common occurrence on many late model Dodge and RAM trucks equipped with a 9.25" axle. The OE ball joints are not serviceable, 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 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 K7460 upper ball joint 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, the K7460 uses a premium neoprene boot with a built-in grease-relief valve, providing a sealed, serviceable part able to flush contamination.
