[QUOTE=1retired06;1096592]Hopefully applying some lubricant will do. Did not work for us. You didn't specify your unit, but at least thru 2015 with mine, belly is two piece, and removable by unbolting crossover supports, and then unbolting the belly itself. Pretty easy. On newer units, a nail gun was used to secure the belly and a major pain to remove those nails and then reinstall. What I have done on ours after I removed the belly once for access to the tanks, was to mark and cut flaps that I can easily open and then seal with Gorilla taped when done. If you have to remove the belly keep your fingers crossed yours is bolted, not nailed.[/QUOTE

To clarify I should have said self tapping nuts, vice bolts.
