An isolation assembly for use with a vehicle. The isolation assembly includes a collar having a continuous wall. A carriage is disposed within a cavity of the wall and is displaceable relative to the collar. A fastener supports the carriage relative to a frame portion of the vehicle. An insulator is disposed between the carriage and the wall of the collar for coupling the carriage to the collar and for isolating the carriage and the fastener from the collar. The insulator has a first portion and a plurality of second portions. The first portion encapsulates one of the second end surface and the peripheral surface of the carriage. The second portions are movable relative to the first portion about a living hinge to encapsulate the other of the peripheral surface and second end surface of the carriage such that the carriage is adequately isolated from the collar.
