Powergear Leveler....stuck

[radi]

Getting the motorhome ready for winter (1995 Southwind), I got 'er parked and put the leveling jacks down. Rear driver's side jack groaned all the way down, so I sprayed some silicone lube on the ram and tried to retract it.
No go. The other two retracted normally.
Unhooked the hydraulic line and it still wouldn't move back up.

I ended up driving up on some wooden blocks, enough to get a floor jack under the cylinder's foot and jacking it back up into place. It squeaked and groaned all the way back up.
Of course while doing so the jack slipped, caught the spring and snapped it.

So, the jack is currently retracted, the return spring is broken, and I unhooked the power to the controller to prevent it from being extended again.

My questions are:
1) where can I get a new spring?
2) What would cause a cylinder to stick like that, even with the lines unhooked?

On the bright side, I'll soon accumulate enough cash-back rewards on the credit card from all these repairs to pay for my first trip


Thanks for any insight...

Take a look there and see what you're looking for. I've got a 99 Pace Arrow and the leveling jacks and springs are probably similar or the same.
My left rear jack leaked so I had to remove it. The cylinder is VERY basic. Fluid pressurizes the piston and it travels downward, when the pressure is released it retracts. The spring that broke is only made to retract the jack when working properly. When I removed my jack the piston moved in and out with almost no effort at all. I'd say there is some rust or debris binding that piston in the sleeve. Either way it needs to be removed and taken to a hydraulic shop. They're out there.
The assembly only weighs about 20-30 pounds. If it's like mine it'll have 6 bolts with 3/4" heads holding it to the frame. Remove the hydraulic line (you already have) and remove the 6 bolts and take it in.
(I've been working on my motorhome since I bought it. Camping World in Chattanooga really took advantage of me since I was a first time buyer. )
Post a picture of the spring if you can't find one.
Hope this helps!
