Been there, recently, after just 2 years of ownership. Look underneath. You may have to remove the underbelly covering (fiddly but not too hard). Check out the mechanism and rails from the motor to the slide-out edge. You might find that the mounting system for main pipe/tub/screw housing is angled a little and not parallel with the chassis and the mechanisms screw housing. The housing is attached to the chassis with a floating pin/gimbal thing on a bracket
On my rig (HG 28RLT) the bracket was assembled at an angle, not parallel, welded like that and painted over, so everybody in manufacturing new about it and left it (caveat emptor). One day the thing it simply seized, thankfully shut and on the settee side not the dining side.
It was going to be too big a job to remove the bracket, break it up at the welds , realign it, re-weld it, then replace it, ensuring that the lengths were still the same (the distances from the main screw to lock nuts to slide-out bracket is critical), so... I packed up the difference with washers. The bolts thankfully were long enough to accommodate this. It isn't perfect but good enough and the slide-out works fine now.
