Wholly crap hahaha I tried to check the o- ring on the pump rod of the Jack .. went smooth till I was putting it back together and the retaining bolts would not start to thread back in with the springs installed tried over and over and over again .. walked away and came back and they finally started .. damn , I’m in a jinxed mode for sure .. but the kicker was , I had to run and get more Jack oil and bleed the air again .. got the air out and lowered the Jack lift and it stopped so I put my foot on it to push it down easy and all of a sudden POW the filler plug exploded out and the Jack oil soaked my ass from head to toe ,, shit tastes terrible and surely blurs your vision .. I can’t find the little rubber plug anywhere . I think it may have blasted off and is no orbiting earth hahaha ! I’m not sure I can even get a new one .. why the hell wouldn’t they have just put a threaded plug in the damn thing is beyond me ! I’ll have to search and check stores and see if I can find something that will work I guess .
