My big slide was not retracting on occasion - had to push it in by hand sometimes - anyway, the 4 outside rollers were NOT rolling - ordered 4 new ones from Fleetwood and replaced - that did help but occasionally, the big slide would not retract - an excellent RV dealer in Las Vegas checked the motor - up to spec - the "fix" was lubing the rails with "slide lubricant" and runnning them in and out multiple times --
Now I spray lube them EVERY time I retract - no further problems !!
