Power Gear Room Slide needs adjustment

Sorry I didn't say it's hitting the side when opening and closing. It's hitting on the rear of the slide on the driver side on the vehicle. This happens opening or closing. It wouldn't come in all the way until I gave it a jerk on the front side and then it popped in place and was able to close it. A few years ago I had Camping World in Madison Wi. pulled it out because of a rivet that broke on the bottom slides. I hope they don't have to do that. We are in Lake Park GA. have an it set up to go into the shop. It has been non stop rain and I don't like standing in the wet to try to adjust it. I'll have to let Camping World take a crack at it. Hopefully it won't break the bank.
Thanks for the info,Happy Camping, bye Dennis
