Trying to upload photo of slide assembly removed from 2004 40 Vectra. To replace the slide supports, I had to completely remove everything from the motorhome. If you aren't comfortable removing everything, I wouldn't tackle this job. I talked to HWH and Winnebago, this is what you have to do.I have better pictures, but it tells me they are to large.
When my large slide with the couch and kitchen in it would go out, it would make a clunking noise, and I had to put a jack under the slide to raise it up, while my wife pushed the button to bring the slide in. I could change the triangular parts, but I could not get to the flat pieces, to change them. I have pictures, & have put some in my profile, but they don't stay there.
I removed everything from one end of slide at a time, it is only 4 bolts holding it to the motor home frame. Two bolts and the end of the hydraulic cylinder are in the bay under the passenger seat. I had 2 floor jacks under the slide to support it. I will try to post more pictures.
HWH - if you get the chance go to their facility in Moscow, IA. 100 feet off of rt 80. They make the parts there and have access to replace/rebuild whatever your issue is. If nothing else give them a call.
I have found them to have great service.
Enjoy Life! It's later than you think. Life changes in a second. There isn't enough time for cheap booze and cheap cigars.
