Abstract: A strut assembly for a vibration isolation device (204a-204d; 450) is disclosed, comprising a piston spindle (408; 458); a first elastomeric member (412; 462) and a second elastomeric member (414; 464) bonded to the piston spindle (408; 458) and in contact with an upper housing (404; 454) and a lower housing (406; 456), respectively; a first strut support (418; 468) and a second strut support (422; 472) attached to or integral with the upper housing (404; 454) and the lower housing (406; 456), respectively; a first strut spindle (420; 470) and the second strut spindle (424; 474) configured to be placed in the first strut support (418; 468) and the second strut support (422; 472), respectively; and one or more removable struts configured to be engaged to the first strut spindle (420; 470) and to the second strut spindle (424; 474), wherein at least one of the first (420; 470) or second strut spindles (424; 474), is removable such that the one or more struts can be replaced without breaking a bonding of the first elastomeric member (412; 462), the second elastomeric member (414; 464), or both.
