Ultra 5000 Power Twin Jacks will not extend

[Pride&Joy]

Hi all!

We have a 2001 Limited (Classic) 30'. I extended the stabilizing jacks down (electric motor) on 1 side but when I went to extend the other side (curb) the jacks would not extend. I used the triangle aluminum "stack" jacks on the side that would not extend. The next day I retracted the jacks. Once retracted, these will not extend. Now both sides are stuck in the retracted position. We've tried the manual crank (removing fuses first-fuses look good) and all jacks seem seized up and will not move at all.

Any suggestions? We have the original owners manual but this does not contain any trouble shooting advice. Any thoughts would be greatly appreciated. We are full timers and are stationary until we leave on Friday AM. Thank you!!!! Angie

Do you get any sound at all when you try to extend them? If not, then there is no power.

Or do you get a clack-clack sound? When that happened to me, I was always able to use the crank to lower it just a little, and then the jack would extend fine.

The crank is a little stiff, but shouldn't be too hard to move.

There are grease fittings on front and rear, but they are pretty exposed to road hazard, particularly the rear.

My experience is from my '98 Limited.

Yes, we do get a clack-clack sound. I will look into adding some grease into the grease fittings once we arrive to Montana where we will be stationary for 6 months. I'll work on the crank also! Thank you!!!

Use a little extra elbow grease on the crank. I found if you could just move it a little (clockwise is down, if I remember correctly) then the motor will catch just fine.

The grease fittings are into the motor gearbox. While you should probably grease them occasionally until you see grease coming out, that is probably not your problem. Once you get the jacks extended, spray the threaded rod with a white lithium grease spray, silicone lubricant or whatever you have or can find. The clack-clack sound is the clutch designed to protect the motor. I find I have to be VERY careful when raising the jacks to not bind them and get the clack-clack or at least my curbside rear will jam and I have to get out the crank. I stop raising them when the motor bogs down just a little and then check to make sure they are all the way up.

Thank you for the info! So I'm understanding, I should raise the jacks to the point where they are up but not to the point where I hear the clack-clack? Basically avoid the clack-clack sound.
Thanks again!
