Stabilizer worm gear adjustment?

Okay I missed this on my 2016 Chaparral MK29. I was working on something else and i realized that the arms were bent on one of the rear stabilizers. I purchased two new arms. The holes are 17.5 in OC. So from the rear of the trailer, the left side complies with that spacing. The ones on the right are 15.5 and the worm drive has bent the arms and the bolt/brackets.
So, how do I make the adjustment worm gear bushing (Traveling part) to put the 2 inches back toward the center? If I turn the gear to correct the right, I will short the left side by 2 inches (Creating the pressure to bend those arms) . How do I adjust, so the two bushings meet in the middle?

Don't you stabilizers work off of separate motors? If so the difference in the arm length should make no difference.

On my travel trailer that had those types of stabilizers, they would sorta self adjust. It should pivot I believe and each should be able to swing. That is, if the above comment isn’t true and you only have one switch for the rear stabilizers? If just one switch, I’d replace them and make sure nothing is bound up. May need lubed

Only one motor on the left side and one long worm gear. So the threaded bearings move simultaneously. The right side placement was off by 2 inches, they don't meet in the middle (They right side has a 2 inch head start). IMO, it was put together incorrectly. Then the first and second time we used it, the extra pressure on the arms caused them to buckle.

Disconnect the leg from the screw and run both to the center and re-attach the leg. It does involve a lot of work and unbolting various things to get the screw and leg separated.

I have it in my head that even if you do adjust the travel block on the lead screw at one end of travel that they won't match at the other end.

Having said that, if you want to try it. Look at your middle pic and you'll see a coupling between the lead screws. You'll notice that the lead screws are opposite hand threads.

I can't see it but that coupling probably has roll pins securing it to each lead screw. Remove the pins and then rotate one screw until the pads match height then reinstall the roll pin(s) back in the coupling to secure both lead screws together.

You'll need to be careful to get the holes in the lead screw(s) lined back up correctly to the holes in the coupling.

Having said that, I think you need to get both set of arms the same length.

Here are a few more pics the bushing in the middle is none threaded and only acts as a bumper. On the bent side, I placed the new bar to give perspective. The left and right side show the head start on the door side.
So, do I have to drop the whole unit and completely disassemble to get the traveling gears to meet in the middle???

Yes, but it's easy to do.

OldCoot, I see it's 6-8 bolts to drop, that's easy. The fun part is how do I get the two threaded to match up with the same "Perspective" starting point. It's one long worm gear. Turn it and they both move, keeping the incorrect starting point on.
Discount the bottom bolts on the legs and extend the travel gear out until the second one is just about to drop (The bent side will have already dropped off) and then put the bent side back on?

If the bent leg is already off, just screw the bolt until the other leg gets to the slot and take that leg off, then just turn the pins both to the center and then holding both pins, turn the screw to where both pins are at the slots and then reattach the legs. I would suggest reinforcing the legs before reinstalling.
