Abstract
An apparatus (10) includes a tie rod (151) for a vehicle steering system. The tie rod (151) has an axis (159), a first cylindrical portion (251) with a first outer surface (261) of a first diameter (271), and a second cylindrical portion (252) coaxial with the first cylindrical portion (251). The second cylindrical portion (252) has a second outer surface (262) of a second diameter (272) smaller than the first diameter (271). The tie rod (151) has a ring portion (281) projecting radially from the second outer surface (262) of the second cylindrical portion (252). The ring portion (281) has a third outer surface (362) extending axially along the second cylindrical portion (252). A boot seal (32) encircles the second cylindrical portion (252). The boot seal (32) has a sealing surface (325) in sealing contact with the third outer surface (362) of the ring portion (281). The sealing surface (325) defines a groove (327) in the boot seal (32). The ring portion (281) is located in the groove (327).
