slide out help on holiday rambler

Thanks for the replies. I'm a general co tractor and usually do my own repairs. But time is my enemy. I took it in yesterday and they are saying it's not the pin but the actual gear. At this point they can't find the part and I'll be into the repair over $300 plus part cost which no one knows. If I could find the part at this point I would just do it. The master slide they want $500. Saying the slide wore grooves and they have to fabricate sheet metal and fill in the groove. Sounds like bs to me. I may be picking it up soon.
