A torque rod assembly includes a pair of end joint assemblies with a thin wall connecting tube disposed between them. The end joint assemblies each include an eye which is friction welded to the thin wall connecting tube. The use of the thin wall connecting tube and the friction welding process allow the friction weld to be located immediately adjacent a bore extending through the eye. The eyes and the thin wall connecting tube can be cast, extruded or formed from steel, aluminum or cast iron.
A mount having a bolt through configuration couples two components of a vehicle. The mount includes a first elastomeric member that defines a first portion of a first chamber and a second elastomeric member that defines a second portion of the first chamber and defines a second chamber. An inner tube assembly defines an opening for receiving the bolt. The first and the second elastomeric members are bonded to the inner tube assembly. An annular member is disposed between the first and the second chambers. The annular member defines a fluid-track which fluidly couples the first and the second chambers. The mount dampens vibrations at varying amplitudes by pushing fluid between the first and the second chambers via the fluid-track. The mount may also include a decoupler by way of a decoupler ring and decoupler cap to isolate the mount at a predetermined amplitude at varying frequencies.

The intimate contact is defined by a pair of weld lines extending along an axial length of the coulomb damper in one embodiment. In another embodiment, the intimate contact is defined by at least a three point contact between the coulomb damper and the component of the exhaust system.
