First, I want to thank those that replied to my previous problem post concerning my steps, I'll have to work on them after the Maritime rally.  I now have a new issue.  Pulled into the park today and my bedroom slide would not go out on our '08 Patriot.  This is the first issue I have had with it.  I crawled under the bed platform to take a look and when the extend button is pushed, I hear the motor run and the exposed shaft coming out of the assembly, the one that has a nut cover over the shaft, is turning but the gears to the bed mechanics are not.  I took the cover and pin off the assembly and nothing appears broken.  I have searched and read a lot on the forum I am still unsure where to start to look or what to test to determine what is wrong.  I suspect from what I have read that it is the brake mechanism.  Any suggestions would be appreciated.
