[Shop-talk] aluminum floor jack

[Randall]

I don't know which model jack you have, but picking one at random from the
HF web site, I see that the warranty is only 90 days (so you're out of luck
there), and there are instructions for filling it.

Before you give up repairing it, I would try calling their customer service
department (believe it or not, there really is such a thing!) and see if
they can order a repair kit for you.  I've gotten parts for other tools from
them in the past, and while it took a long time (over a month as I recall),
I did eventually get the parts and the price was not unreasonable.  (Not
cheap either, but better than throwing the tool away.)
