I use a pair of vice grips and some serious muscle on my Power Gear springs.
On the HWH the pad is on a ball mount it can tilt a bit and you can just hammer or jack it back to level.. To jack back (assume this is a 2 spring jack)
Put floor or bottle jack under low edge of jack, Jack it up, pad should level, IF using a floor jack you might be able to go a bit past level but do not try this with a bottle jack.
Hook up spring, Remove hand jack, extend power jack, and retract, all should be good.
Home is where I park it!
