wobby automatic RV steps. solved

My power steps were vibrating like crazy when they're fully extended or retracted. clearly something was wrong. I ordered a new No-Name motor off Amazon for around $30. tried a few times installing it and then I finally realized the silver shaft of the motor by the gear has to be inserted into the frame properly to maintain alignment!!!!! The bushings that were on the previous motor were too long not allowing the motor shaft to get into its respective housing. I created shorter bushings with the series of washers and nuts. Hope it helps.
