Replacing the rollers on a bedroom slide-out

[darbyjudy]

I have a 2004 Gulfstream Sunvoyager model #8379 and the bedroom slide-out has a bad roller on the left side. I intend to replace this myself. Went to Longview today and they tell me that Gulfstream does not have the roller I need anymore, can you imagine four years and a part obsolete. So they sold me one that looks to be close. Now I am not sure how to go about replacing this roller. I know I will have to run the slide-out out part way to get axcess to the roller, but not sure how to support the slide while I remove the roller. Has any of our fine member done this repair and if so how do I go about it. Thanks to all.
