Hello everyone I have a Walker 93660 floor jack and I am having issues with it. I replaced the seals in the power unit and replaced all the balls and springs, now when I jack it up it goes up fine but when I move the handle up to pump again I can see the front of the jack drop just a little. Then when I put it under a load it wont lift the load but you can fill the handle get tight and it fills like it is working. I talked to someone people and the said to seat the balls so I did that and it stopped dropping but later it started it again. Can someone please help me?
