Locking boot for ball joint
An automotive component having an opening through which a ball joint extends, the ball joint comprising: a housing having an exterior substantially cylindrical surface, a seating surface radially extending from the exterior surface for abutting an adjacent first side of the automotive component, and a peripheral groove disposed in the exterior surface spaced axially from the seating surface a predetermined distance; a ball stud having a ball end mounted within the housing and a shank extending axially out of a crown of the housing; a flexible boot having an distal end sealingly engaged on the shank and an opposing proximal base end, the base end including a metal base ring with an inwardly extending flexible detent engaged in the peripheral groove in the housing and a base seal sealing engaged on the exterior surface, the base ring having a radially extending abutment surface for retaining an adjacent second side of the automotive component, and wherein the automotive component is selected from the group consisting of: a control arm; a stabilizer link; a stabilizer bar; and a steering linkage.
1. A ball joint, for mounting into an opening through an automotive component, the ball joint comprising:
a housing having an exterior substantially cylindrical surface, a seating surface radially extending from the exterior surface for abutting an adjacent first side of the automotive component, and a peripheral groove disposed in the exterior surface spaced axially from the seating surface a predetermined distance;
a ball stud having a ball end mounted within the housing and a shank extending axially out of a crown of the housing;
a flexible boot having a distal end sealingly engaged on the shank and an opposing proximal base end, the base end including a metal base ring with an inwardly extending flexible detent engaged in the peripheral groove in the housing and a base seal sealing engaged on the exterior surface, the base ring having a radially extending abutment surface for retaining an adjacent second side of the automotive component against axial movement relative to the housing.
2. The ball joint according to claim 1 , wherein the base ring has an annular exterior wall extending from an outer periphery of the abutment surface.
3. The ball joint according to claim 2 , wherein the base ring is formed of sheet metal and the detent comprises radially extending resilient tabs.
4. The ball joint according to claim 3 , wherein the tabs extend from an inner periphery of the abutment surface in an axial direction toward the crown of the housing.
5. The ball joint according to claim 1 wherein the peripheral groove in the housing has a radially extending detent surface.
6. The ball joint according to claim 5 wherein the peripheral groove in the housing has a tapered surface extending from a radially inward edge of the detent surface to the exterior substantially cylindrical surface of the housing.
7. The ball joint according to claim 1 wherein the crown of the housing has a distal crown diameter less than an at rest inner detent diameter.
8. The ball joint according to claim 1 wherein the base end of the flexible boot includes a laterally extending installation flange of flexible material joined to the metal base ring opposite the abutment surface.
9. The ball joint according to claim 8 comprising a tubular installation tool having an annular contact end engageable with the laterally extending installation flange of the flexible boot and an impact end opposite the annular contact end.
10. An automotive component having an opening through which a ball joint extends, the ball joint comprising:
a housing having an exterior substantially cylindrical surface, a seating surface radially extending from the exterior surface for abutting an adjacent first side of the automotive component, and a peripheral groove disposed in the exterior surface spaced axially from the seating surface a predetermined distance;
a ball stud having a ball end mounted within the housing and a shank extending axially out of a crown of the housing;
a flexible boot having a distal end sealingly engaged on the shank and an opposing proximal base end, the base end including a metal base ring with an inwardly extending flexible detent engaged in the peripheral groove in the housing and a base seal sealing engaged on the exterior surface, the base ring having a radially extending abutment surface for retaining an adjacent second side of the automotive component against axial movement relative to the housing, and
wherein the automotive component is selected from the group consisting of: a control arm; a stabilizer link; a stabilizer bar; and a steering linkage.
