An isolation mount for use in a motor vehicle is disclosed. The motor vehicle has a body portion and a subframe portion. The subframe has a through hole. The isolation mount includes a thimble member having a flanged portion and an axially extending tube portion. An annular foamed elastomeric member is adjacent to the thimble member. The annular member having a radially outwardly extending one end portion, an opposite end portion and an inner passage. The opposite end portion is acceptable in a slidable fit into the through hole from one side of the subframe portion to the other side. The opposite end portion being movable radially outwardly when the opposite end is axially advanced past said through hole and said one end portion being axially advanced to be adjacent to the one side of the subframe portion. The length of the annular member is related to the length of the through hole so that when the tube portion is inserted into the inner passage at the opposite end portion, the thimble member advances axially toward the one end and the flanged member compresses the radially outwardly potion until the end of the tube portion is adjacent to the one end portion of the annular member. Optionally, a rubber bushing member is disposed around the axially extending portion to improve the stiffness and the stiffness rate in the lateral and fore and aft directions.

1. A combination of a vehicular subframe and an isolation mount, the combination comprising:a vehicular subframe having a first surface, a second surface, and a through hole that extends between the first and second surfaces; and an isolation mount including a tubular member and an isolator, the tubular member including a tubular portion and a flange portion; the isolator including a top portion, a bottom portion, a middle portion connecting the top and bottom portion and disposed within an outer periphery of the top and bottom portions, a through hole, and an annular hinge formed in the outer periphery of the middle portion of the isolator, wherein the isolator is inserted into the through hole of the subframe so that the top portion of the isolator is adjacent the first surface of the subframe and the bottom portion of the isolator is adjacent the second surface of the subframe, wherein the tubular portion of the tubular member is inserted into the through hole of the isolator so that the flange portion of the tubular member compresses the top portion of the isolator to move the top portion radially outwardly of the through hole of the isolator, wherein the hinge of the isolator facilitates the compression of the top portion.
