Saved.My jack is leaking down worse now. I am thinking about buying a new one. I get really annoyed when it doesn't lift high enough, so I decided to research the different lift heights and specs. I decided to post this up to help others. I'm thinking about the one that goes over 24" high.

Wife's yukon xl has a tire with a slow leak. Put my jack (old northern tool one I think) under it, get rear tire off the ground, slowly rotating tire, tire touches ground... jack it up again, rotate, leaks down... I've already added oil to it a year or so ago, guess it's time to replace.
