The parts that most often fail on a hydraulic jack are seals. Usually easy for most weekend mechanics to repair (often simple o-rings). If you can work on brakes, clutch, and other hydraulic systems, you can fix most jack problems yourself. A decent hydraulic jack can last a lifetime with a seal change every now and then.
Dirt is another common problem with an easy fix - tear it down, clean it out, put it back together with fresh fluid.
