We slipped this one in as our customer needed to get to Florida for a surgery. The customer called in and said that their slide out in their new Thor coach wasn’t working again… after diagnosis we found there was no power to the switch. Once that was addressed we removed the wire harness and inspected, pulled an a few measurements take sure the gear racks and slide out were square. Everything was within spec. Although both motors were the same size one was not up to speed. To avoid future issues we replaced both motors and apiex crc power lube to the racks. Our customer is now heading back to Florida and their faith has been restored. Call the best rv service center around 574 642 3365.
