Step not retracting completely "jackhammering' (UPDATE)

[klutchdust]

Opened the door the step didn't come out completely. Closed the door and it was sluggish. Lubed all points and checked it the next day. When it attempts to go into the fully retracted position it starts to jackhammer. I went underneath and had dear wife open and close the door and i can't figure it out. It will not retract completely. The other day when it was acting up I gave it a push with my foot thinking maybe corrosives or dirt on it. It worked ok. Now jackhammer. I turned it off it's in the open ready position.

yup, did exactly that and it works fine. Gears are metal. Lubed well and re installed.

I changed out the motor on BIL's Monaco and used a power window motor from an older Ford. Don't remember which one it was though. The motor works fine. I watched two videos and saw the gear assemblies in question. IF the larger of the two gears is the one that failed it makes sense that turning it 180* and using the newer side would solve the issue. The coach is a 2009. If the gears lasted that long they may go another 10 years. It's a simple fix and not an issue for me to try.

Mine does not have a warning light however if it did my first choice would be to check the electrical connections at and near the step. Unplug and plug back in or look for a wire loose. If the step has a ground wire check that.

THIS! ^^^^ Just spring for the new motor, though. Gear teeth may be getting brittle and may break again quicker.
