Ball joints facilitate kinematic motion of the suspension while keeping it bolted together. Pressed into knuckles or control arms, ball joints act very much like the ball-and-socket mechanism of a human knee, elbow and hip.

Metaldyne Ball Joints
Metaldyne manufactures ball joints to meet customer requirements using industry-leading designs and value-added services such as rapid prototyping, load projections, ball joint sizing and comprehensive testing. The key design benefits include:

• Low-friction lube-for-life - delivers improved suspension frequency response, maximum life and serviceability, packaging flexibility (based on a variety of designs), and elimination of the need for intermittent service
• Integrally molded press-on seals - reduces damage due to external clamp-ring installation, provides option of neoprene or silicone seals, and allows for ease of assembly

Metaldyne's ball joint manufacturing expertise and processes also offer benefits:

• 100% in-line leak test - ensures no leaks in field service
• 100% in-line torque monitoring and in-line end play - to ensure sub-component uniformity
