    hey guys

    I have a 5th wheel trailer with 2 landing gear legs

    I went to hookup to the trailer and 1 of the legs wont slide up when I remove the Clevis pin

    I tried heating up the leg and using a floor jack to push it up. the problem is it is lifting the entire trailer

    What do you suggest I do?

    Did you try going down with it, just to see if it will move?

    Whack it with a sledge hammer with some weight on it.

    Is there a lifting mechanism, or is it moved by hand?

    It is that portion that moves by hand when you pull the pin out

    Yes it used to slide all the way up before without any problems before getting stuck

    I tried whacking it with a sledge hammer but it didnt help

    I tried heating it up with a torch and whacking it but it didnt help

    I tried using a floor jack and that moved it one pin notch higher but after that it kept lifting the entire trailer

    Why don't you remove it completely and look up into the receiver to see if there is an obstruction ?

    Bolt a piece of angle iron on bottom leg to put a bottle jack on.Run a 4x4 across both sides of trailer FRAME over the jack.
    A bottle jack on both sides would be ideal to press straight down.

    only problem that I don’t know about is how much pressure the main mount above will take?

    ‘Remove the foot plate and use a mirror to look up inside?

    looks dangerous to me!

    Is it worm drive for up-down? Maybe it’s broke and jammed in.?

    Check the fixed and moveable parts for twist. You may be able to get it to move if you run a bar through the holes on the lower part and twist it back and forth.

    That bottom leg must be bent. It will need to be taken out and be replaced.

    I went thru this with my fiver. I had a leg jam in Phoenix and I had to tow back to Arkansas without unhitching. A helpful RV park neighbor tried to help me jack it up to take the weight of the leg but placed the jack on a non structural piece of square tube and only succeeded in jamming my front cargo box door. So heed the advice above and make sure you're jacking on a frame member.

    I called out a local trailer repair guy and his son. They placed jacks on both sides of the trailer and slowly jacked up both sides evenly so as not to twist the frame. Once the weight was off the landing legs and the jammed leg was about 6" off the pavement, they removed the flat shoe, drifted out the locking pin (which was bent) and forced the inner leg back up into the outer leg with a third jack. If you're very lucky it may be that only the locking pin is bent and the inner leg may slide into the outer without force. If not you'll have to replace the whole leg assembly which could require cutting away welds and rewelding the new replacement leg depending on the clearances involved. I let my pro RV guy fix it when I got back to AR. The part cost me $471 and the labor $550. LCI in their infinite wisdom does not sell just an inner leg, you have to buy the whole assembly. I boxed up my original drive motor for a spare, it was still good. Maybe you could get a used one somewhere.

    Hopefully YMMV. I feel your pain.

    As an afterthought, I debriefed myself as to what caused this. It was a 2014 unit I bought used, so the PO may have precipitated it. However I may have unwittingly done it due to my inexperience with hitching 5'ers. Make sure you have the rig securely chocked (no movement) when you back up to hitch. Also make sure the hitch shoe on the trailer is slightly below the shoe on the truck hitch. You want to lift the trailer but not push it back when you hitch.

    Good luck.
