Could be a simple lube issue? The jackscrews tend to accumulate a lot of grit on the threads, making them really stiff. Every few months, I run each jack up and down while holding a wire brush against the threads to clean them. Once cleaned, I spray the threads, and all the sliding joints, with a Dupont Teflon (not silicone) lube available from Lowes but not Home Depot. Run the jacks up and down a couple more times, and they get really easy.
I don't do all the cranking by hand, of course. A cordless drill makes it all pretty easy.
