Question
I have a2007 keystone fusion toy-hauler and the kitchen slide jumps onthe rack& pinion,how do you ajust it. Thanks Jack

Answer
I need just a little more information can you tell me if the pump is made by lippert lci1 or hwh. is it driven hydraulic ram or electric motor. is there what look like cog gears running on a track or does the gear have holes in it where the room moves out. Is this a flush floor or above floor  slide main living or bedroom.
