Replacing the seals and changing the jack oil on my Harbor Freight (US General) Floor Jack and Craftsman Floor Jack. Both jacks were leaking or didn't hold any pressure when under load. Had to figure out which seals were bad and changed them. Replaced the oil with some Bars Jack Oil with Stop Leak.

Viton O-ring Kit (better than ones I used) - https://amzn.to/3irkNsr
Viton are don't expand and are oil resistant. I used regular Nitrile O-rings which will deteriorate quicker.
