ABSTRACT:
A tripod universal joint includes a shaft with a forked end or tulip which is held in assembled relationship with a tripod spider by a spring clip having angularly spaced legs adapted to snap releasably into grooves in the tulip. The spider is located in a cup-shaped housing. To facilitate assembly of the tulip with the spider, a resiliently flexible washer is placed on the bottom of the housing and holds the spring clip upwardly in a position permitting the legs of the clip to interlock with the tulip when the tulip is moved axially toward the clip. After assembly of the tulip with the clip has been completed, the spacer washer is removed from the housing by pulling on a flexible retrieval wire which is attached to the washer.
