Abstract
A bushing block for use with a trunnion assembly of an independent suspension integrates a bearing cap and a bushing into a single component. A face seal is installed on a trunnion pin of the trunnion assembly. The bushing block is next assembled on the trunnion pin, the bushing block contacting the face seal. The trunnion assembly is installed on a lower control arm assembly, a pair of cap screw apertures on the bushing block aligning with a pair of cap screw apertures on the lower control arm assembly. Cap screws are installed therein. Grease grooves are formed on the interior surface of the bushing block to allow grease to flow down the exterior surface of the trunnion pin, eliminating additional machining on the trunnion pin.
