Floor jack stopped jacking

[Jay5.9L]

I have a older harbor freight floor jack that has served me well over the years. Haven used it much recently and now it won’t jack up.

The hydraulic oil is full and I followed the bleeding instructions. Anything I can do to fix it or is it time for a upgrade?

Do you have any leaks? If not, it sounds like an internal seal is not working. You might be able to get by with jack oil with stop leak in it

No leaks at all

It's likely the piston seal. Or the blead orifice seal.

The one in mine went and HF (while they don't warranty the new ones past a year or so) did give me original value towards a new one since the old ones carried a long warranty.

I would say that’s jacked up, but obviously it isn’t.
