I think my 98' Rockwood freedom 2280 lift system is in need of repair. This will be my second season with it and I first noticed a problem while raising the roof and I would hear a loud POP. My initial reaction was "OK that sounded like a cable breaking, here comes the roof it's gonna come crashing down", but instead it just kept cranking up( after I changed my shorts). This is my first popup or experience with one, so I'm not sure how hard the cranking should be, but it seems to me that it's too difficult. I'm in fairly decent shape and I'm winded after raising the roof. Is there bearings in the crank assembly that need to cleaned/greased. I would really like to replace the whole crank assembly cause it's been out in the elements for its whole life and is pretty rusted up but I can't find anything. Does anyone have similar or info on how to fix this problem. Also I did a search before posting, but all I could find is what looked like different Rockwood lift systems. I'll try to post some picks of what I have.
