The bolt holds a half moon gear in place so when the door opens the motor turns , turning the half moon gear and either extends or retracts the steps. The thin metal bracket that holds wires and clips would have to be removed to access the 'socket' that the bolt sheared off in, under the units . I'll clicka pix of the bolt to give you a size estimate. Thanks again. My inability frustrates me, so I really do appreciate you sharing your wisdom.class A entry stepsWe have a 2012 Thor Challenger 32v that we've put about 10k miles on. We've dealt with various "new" break in problems successfully, however the other day heard a bang after pulling in and shutting off engine. Exited the unit to check, thinking may have hit something. Couldn't find any reason for the noise. Entered the unit, closed the door and 'Bang' again. Went to exit and no steps. Inspection revealed there is a 1" diameter bolt holding a half moon gear in place that rides on a gear from the motor, which sheared off below the mounting plate just above the threads. Why would this happen? Metal fatigue? I believe it requires removing another bracket and drilling out the remaining piece of bolt to be replaced. That's some tough metal! Anyone know if I am even in the ball park on this or do I replace the entire unit? Thanks for any help.
