So we've got a Harbor Freight floor jack that squeaks as weight is applied to it when raising a vehicle. Now I've used this thing while it was raining and when snow is on the ground so I have a feeling that is a large cause of this. I sprayed everything down with WD-40, but haven't used it since so I don't know if it worked or not. Is there anything else I should do? I was also thinking of regreasing the body with the supplied fitting.
