Wondering if anyone would know whats wrong with my floorjack. Its an aluminum craftsman and never gave me a hint of trouble in the 2 1/2 years iv owned it till today. I went to jack my car up and the initial 2-3 start pumps were fine, but once the car got higher and more weight on the jack it wouldnt jack till the handle was pretty much all the way down and it would give me about a 1/4" literally, of a pump at a time. Took me forever to get the car up this way as you can imagine. Anybody have any ideas on what could be wrong?
