Electric Tongue Jack

Had my UltraFab jack lockup too. The pin block, under the allen head screw, had sheared. If the jack is driven all the way up, or all the way down, the travel will stop, and the motor will continue to push until the pin shears, as it's designed to do.

Poor design by the manufacturer. Should have limit switches so it can never go beyond the limits.

The replacement pin was hard to find on their website. I contacted customer service, and they sent me this link:

I bought 2 of them. Now I have a spare, just in case. I'm now very careful not to drive the jack too far either direction. No further issues two years later.

When I purchased my new TT, It came with a manual Jack, I purchased an electric jack from Harbor Freight for $120.00 with the 20% off coupon,
When i got home I disassembled it and greased all the parts then made a cover for it, so far so good. My Cousin bought one and he did them same thing several years ago and has had no problems so far..You might check the inline fuse, then if necessary raise the tongue to get pressure off,
ans see if maybe it is jammed, You might have to either buy a new one or purchase a mechanical jack and use until you can get yours repaired.

Blown in-line fuse? Try taking the pressure off the jack with a bottle jack and then turn it manually. If its truly locked up then something in it has broken and wedged in the gears or screw. put it onto the hitch ball for safety before you start taking it off if it comes to that. They aren't complicated to work on.

Can't help you with the immediate problem, and others have given suggestions. Another suggestion, should this happen in the future, or for anyone else...keep your old manual jack. When I replaced mine with the electric jack, I kept the old one. Should the need arise, put down the stabilizers and with a few hand tools, remove the electric jack and replace with the old/original jack. My install took maybe 15 minutes, the uninstall would probably be about the same.

If you can't easily find the problem, I'd buy a new jack. Several available for under $200 with free shipping.

:) Hi, my tongue jack stripped gear while I was on the opposite side of this country. I was unable to find/buy a new gear, so I had to buy a new tongue jack. (at an inflated price) When I got home, I took my old tongue jack apart. It was jammed, but I was able to un-jam it. I ordered a new gear on line and my old tongue jack is now fixed. Point being, it can be un-jammed and parts can be bought.

You might try lifting the tongue with a manual jack to get the load off the electric jack and then see if if can be moved with a crank or electrically. I'm thinking that if the screw in the jack is bound up it could be stripping so be careful of it falling if it should fully fail. If you can lift the tongue with a manual jack then remove the electric jack and then lower the tongue onto your tow vehicle ball for safety. Then you can replace the tongue jack with whatever you have that works.

you should be able to take the top off and see if a gear is broken or the gear shaft broken, I use to take mine off and grease it up every so often when I had a TT. Good luck.
