A guide assembly for a rod of a motor vehicle strut, comprising: a tubular housing about an axis, said housing having a first end and a second end; a disc having a first surface and a second surface disposed within the housing, said disc first surface adjacent housing first end; a flexible assembly coaxially disposed within the housing adjacent the disc second surface, wherein the flexible assembly defines at least one opening for carrying a fluid; a primary seal positioned coaxially within the flexible assembly, said seal having an inside diameter engaging the rod and an outside diameter engaging the flexible assembly; a rod guide disposed adjacent the primary seal and coaxially within the flexible assembly; a bearing disposed adjacent the primary seal, said bearing positioned between the rod and the rod guide; the flexible assembly comprising a flexible member molded to an inner insert and an outer insert, said inner insert having an inner diameter adjacent the rod and said outer insert having an outside diameter adjacent the housing; a buffer seal disposed adjacent the bearing and opposite the primary seal, said buffer seal coaxially positioned between the rod and the rod guide; a retainer disposed adjacent the buffer seal and coaxially within the housing, said retainer configured to press fit into a groove at the second end of the tubular housing, said retainer engaging said flexible assembly and said first end of tubular housing with said disc disposed therebetween; whereby radial movement of the rod induces deformation of a flexible member and negligible friction between the flexible member and the housing; and wherein the rod guide is made of a porous material compatible with MR fluid, said rod guide configured to filter the MR fluid and enable lubrication of bearing and primary seal with carrier fluid. a tubular housing about an axis, said housing having a first end and a second end; a disc having a first surface and a second surface disposed within the housing, said disc first surface adjacent housing first end; a flexible assembly coaxially disposed within the housing adjacent the disc second surface, wherein the flexible assembly defines at least one opening for carrying a fluid; a primary seal positioned coaxially within the flexible assembly, said seal having an inside diameter engaging the rod and an outside diameter engaging the flexible assembly; a rod guide disposed adjacent the primary seal and coaxially within the flexible assembly; a bearing disposed adjacent the primary seal, said bearing positioned between the rod and the rod guide; the flexible assembly comprising a flexible member molded to an inner insert and an outer insert, said inner insert having an inner diameter adjacent the rod and said outer insert having an outside diameter adjacent the housing; a buffer seal disposed adjacent the bearing and opposite the primary seal, said buffer seal coaxially positioned between the rod and the rod guide; a retainer disposed adjacent the buffer seal and coaxially within the housing, said retainer configured to press fit into a groove at the second end of the tubular housing, said retainer engaging said flexible assembly and said first end of tubular housing with said disc disposed therebetween; whereby radial movement of the rod induces deformation of a flexible member and negligible friction between the flexible member and the housing; and wherein the rod guide is made of a porous material compatible with MR fluid, said rod guide configured to filter the MR fluid and enable lubrication of bearing and primary seal with carrier fluid.
