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 (18, 20) in its exterior surface with a serpentine shaped inertia track (26) in the outermost surface of the elastomeric body to provide communication between the recesses. A window metal sleeve (16) is encapsulated within the elastomeric body by mold bonding, and the window metal sleeve has a longitudinally spaced apart pair of rings (30, 32) above and below the level of the recesses, respectively, and a diametrically opposed pair of webs (38, 40) extending between the rings. A plurality of outwardly projecting pads (28) is located in one of the webs in the region of the inertia track to prevent deformation of the inertia track under load. The annular elastomeric body is inserted into an outer metallic sleeve (36), while the sleeve and the elastomeric body are immersed in a damping fluid, and the diameter of the outer sleeve is then reduced by a swaging process to tightly seal the sleeve against the annular elastomeric body and to seal the damping fluid in the recesses and the inertia track.
