I wonder if the pivot pin on one side is tight?
Not sure yet but all pins look well greased. There is no squeak or anything so im guessing the pins are ok. Thanks

It's impossible to have two cylinders, with their various linkages and pins and pivots have the exact same resistance.

That's what the torque tube is for, to tie both sides together so they stay in time.

If you have something hanging up enough on one side that you can visually see the torque tube under stress you have an issue. You have to find out what is binding causing one side to lag.

You can try unpinning the cylinders from the SSQA plate and see if the plate moves freely as well as the 4-bar links. You can try swapping hoses and see if the lagging cylinder follows the hoses.

But the torque tube "should" be stout enough to keep things lined up and overcome a little resistance if one side is a little tighter than the other

That's what I would do. Pull the cylinder pins and see how it moves. If it moves easily, then you know you have a hydraulic restriction.

Sounds like 1 side is getting air in it and once you push it out they synchronize again. I repaired a slide on a friends motor home once where this was the case , had to replace the lagging cylinder which showed no signs of leaking .
