If you are removing the motor on a 2010 Keystone Raptor 3912LEV Rear Stabilizer Bar, the tool shown will not work. I have tried 4 different tools from several dealers with no success, they are too thick to fit in the mechanism that the motor shaft goes into. I removed the shaft from the removed motor and inserted it into a drill bit extension from the hardware store. I use it with a cordless screwdriver and it works great.
