Put a car jack under the tongue, unbolt the jack, and lower it onto your ball. Manual lifts can be bought at Tractor supply and Northern Tool or most trailering stores.
I don’t know for sure, but I’d imagine there’s a reduction gear train inside the head that takes the (relatively) weak 12V input and turns it into torque that can raise ~800-1000 pounds with little strain. Your video sure sounds and looks like broken gear(s) to me (you can see AND hear the pulsing), and if that’s the case, it’s likely not repairable BUT manually cranking the jack with the on-order tool should at least get you up and down as needed (the wrench/driver is working directly on the threaded shaft of the jack; the motor is likely trying to drive a pinion into the threaded shaft (which works like a worm gear). To save some wear and tear on your shoulders, I’d measure that bolt head and see if there’s an applicable socket you can buy. You could chuck that into an impact/drill and use that to actuate the jack too…
Good luck!
It’s broke, you need to just replace it. Even if you can somehow get it freed up using manual crank your just prolonging the inevitable. Then it will wait to completely crap out at the worst possible time. Power tongue jacks are not very expensive and super easy to replace
That stinks.
This is the exact reason why I’m reluctant to switch from a manual jack to an electric jack. So many small things can go wrong.
Check to make sure you have enough voltage in your battery before getting too mad at it, sounds to me like a lack of power.
If it is stuck, you might use a floor jack or the jack from your car to help the tongue up a little to remove the pressure from the jack.
Lastly, you can use a socket to turn the jack, you don’t have to have the special tool.
Lmao there’s bits of the assembly all over the inside under the cover
Franticly googles tongue jack emergency crank…
