Abstract
An automotive vehicle has a door adapted to pivot about a generally horizontal pivot axis, with the door including a shell defining a space surrounded by the shell. The door is pivoted upon bearings located at each end of the door. A torsion bar lift assist is provided with a vibration and noise isolator and damper, which is engaged about a central portion of the torsion bar. The damper prevents objectionable noise which could otherwise result in the event that the torsion bar strikes the shell of the door because of road-induced vibration.
