Abstract
A tie rod end having a purgative zerk for removal of used lubricants is provided. In one embodiment of the invention, the tie rod end includes a socket member that defines a first bore in which a ball stud member is disposed and a second bore in communication with the first bore. The purgative zerk is disposed in the second bore. In a second embodiment of the invention, the purgative zerk is disposed in a plug used to close one end of the first bore. The use and location of the purgative zerk enable purge holes to be eliminated from a boot seal disposed at one end of the first bore thereby reducing contamination of the tie rod end.
