It would be nice to know if that gear is available on a retail basis and if it is, where did you get it from. I don't think Kwikee sold parts and Lippert is even stingier with information and parts than most.
A temporary fix some have suggested is to relocate the gear as only a small portion of the gear is actually used. Emphasis on "temporary"!!!
By the way does anyone remember when Kwikee sold to Lippert?
