A fluid damped bushing (10) comprising a metallic sleeve ( 12) and an annular elastomeric body (14) mold bonded to the exterior of the metallic sleeve. The elastomeric body has a spaced apart pair of fluid containing recesses ( 16, 18) in its exterior surface with an intermediate recess (20) positioned between the fluid containing recesses. An inertia track plate (22), which is formed from a relatively rigid material, is positioned within the intermediate recess, and the track plate has a flow passage (24) formed in its exterior surface, opposed ends of the flow passage being in fluid communication with the fluid containing recesses. The bushing is circumscribed by longitudinally short, metallic rings (26, 28) on longitudinally opposed sides of the recesses, and is then tightly surrounded by a metallic sleeve (30) which has an elastomeric inner liner (32) mold bonded to its interior surface. The elastomeric body also has a second intermediate recess (34), which is like the intermediate recess (20) and which is diametrically opposed thereto, and the second intermediate recess is also fitted with a track plate (36). The track plate (36) is like the inertia track plate (22), except that the track plate is not provided with a flow passage corresponding to the flow passage (24).
