Well here is the deal.
Jayco had 2 guys come out from a mobile mechanic place. They traveled 90 miles to get here in ft Stockton Tx.
They had to tear the entire unit out to fix a loose net that the motor spins to actuate the slide.
Jayco said you should not drive the slides till they click as it is hard on the clutch. The slide just uses a bellville washer that when the motor loads up slips and makes noise. Jayco said mark the floor or get good at stopped the slides before the clutch engages.
I've had jaycos since 1998 and this is news to me and I hope for you also.
