The bores defined by the strut are aligned relative to each other along an axis. The methodology of the present disclosure further includes the step of: pressing a brake pin bushing into each bore of the strut in a direction extending away from the longitudinal axis of the strut with each brake pin bushing having first and second ends, and wherein a periphery of each bushing has a frusto-conical surface configuration. A railroad freight car strut assembly is also disclosed.
