Shock Absorber Struts

I disassembled and clean the left strut. I replaced the O rings, polished the piston, cleaned and honed the cylinder, and replaced the hardware. The photo shows it disassembled next to the right strut that’s still in sorry shape.  The struts are filled with a petroleum based hydraulic fluid that helps dampen landings.
