Ball Socket
Volvo

Designed as the articulating end in steering and linkage assemblies, the Ball Socket provides a precise, pivoting connection that accommodates angular movement while maintaining a sealed interface against dirt and moisture. Produced to tight tolerances, this joint minimizes play, preserving steering geometry across the harsh temperature and load cycles typical of heavy-duty Volvo applications. The spherical bearing accepts a stud-end or arm boss, distributing load evenly and reducing localized stress on linkage components during cornering, road shock, and heavy braking. A robust finish and streamlined edge geometry reduce wear from abrasion and help retain lubrication within the bearing cavity, extending service life in demanding service bays and on remote routes. In service, the Ball Socket contributes to consistent steering response, improved return-to-center feel, and predictable handling after impacts that would otherwise introduce excess play. It integrates cleanly with OEM control arms, knuckles, and tie-rod assemblies, delivering a plug-and-play replacement that preserves alignment and ride characteristics. Properly configured pivot joints like this are critical for tire wear management and steering safety across Volvo heavy trucks. Source One Parts Center.
