Abstract
A vehicle, a prop-shaft and a method of reducing noise in a vehicle are provided. The prop-shaft includes a cylindrical shaft having a hollow interior. A liner is positioned within at least a portion of the hollow interior. A first retaining member is disposed adjacent an end of the liner, the first retaining member sized to inhibit movement of the liner in a first direction. A second retaining member is disposed adjacent an opposite end of the liner from the first retaining member, the second retaining member sized to inhibit movement of the liner in a second direction, the second direction being opposite the first direction.

A prop-shaft for a vehicle comprising:
- a cylindrical shaft having a hollow interior;
- a liner positioned within at least a portion of the hollow interior;
- a first retaining member disposed adjacent an end of the liner, the first retaining member sized to inhibit movement of the liner in a first direction;
- and
- a second retaining member disposed adjacent an opposite end of the liner from the first retaining member, the second retaining member sized to inhibit movement of the liner in a second direction, the second direction being opposite the first direction.
A vehicle comprising:
- an engine;
- a rear differential;
- and
- a prop-shaft operably coupled between the engine and the rear differential, the prop-shaft including:
- a cylindrical shaft having a hollow interior;
- a liner positioned within at least a portion of the hollow interior;
- a first retaining member disposed adjacent an end of the liner, the first retaining member sized to inhibit movement of the liner in a first direction;
- and
- a second retaining member disposed adjacent an opposite end of the liner from the first retaining member, the second retaining member sized to inhibit movement of the liner in a second direction, the second direction being opposite the first direction.
A method of reducing noise in a vehicle, the method comprising:
- identifying a location of a first anti-node and a location of a second anti-node of a prop-shaft that operably couples an engine to a rear differential, the prop-shaft having a hollow interior;
- positioning a liner between the location of the first anti-node and the location of the second anti-node;
- retaining the liner in a first direction with a first member;
- and
- retaining the liner in a second direction with a second member, the second direction being opposite the first direction.
