The Dinan tension strut ball joint kit replaces the compliant rubber bushings in the front tension compression arms with sealed monoball spherical bearings carried in machined aluminum housings. Removing that bushing deflection sharpens steering response and reduces brake shimmy, while nylon lined bearing races keep the joint quiet enough for daily driving. One kit services the complete front axle, shipping with two monoball and carrier assemblies, retaining caps, spacers, stainless mounting screws, and the Loctite 609 retaining compound that assembly requires.
