I replaced springs on HWH jacks, and found a post that suggested with the jack fully extended, insert a bunch of pieces of broken off ice cream sticks to keep the spring extended when the jack retracted so you could remove it easily. IT WORKED GREAT.
You put sticks down opposite sides of the spring to keep it straight when the jack is retracted.
You put IC sticks in the new spring before you install it, then pull the sticks out after the spring is installed with the jack fully extended. This was a bit more effort but also works great.
You can buy IC sticks on line or at any hobby store.
