My AutoZone D95004s just quit working this winter after 4 years. I found O'Reiley's had Sachs SG314002s in the warehouse. After putting on TWO SETS, it seems that they don't hold like they used too (maybe they have a shelf life as the packages looked OLD/dusty).
Anyway, I mixed and matched old and new and have the rear hatch satisfactorily lifted for now.
Is there a minimum pressure that should be able to hold a non-wing, 73 hatch? How can I test them (in my garage) before installation?
