When I operate the landing gear on my 2007 Big Horn 3055RL I hear a clicking noise. The source seems to be on the port side below the motor that drives the landing gear. A bolt and nut that connects the shaft below the motor is hitting the bottom of the motor as the shaft rotates. This has caused a gouge in the bottom casing of the motor. The motor is loose. I am able to tighten two of the bolts that hold the motor up, but the other two won't tighten so the motor still sags. I don't know if they are stripped or there is a nut on the other side that just keeps turning. Any ideas on how to fix this would be greatly appreciated.
