Sticking slide

Denali 289RK. The main slide is roughly 14 ft long. It all of a sudden started to stick so bad on the left side, I almost couldn’t get it to slide out on this trip. Goes in just fine. Last season, the whole slide would start to go out on the bottom but the top seemed to bind up. Then would “pop” and go out fine. This trip, I had to stand inside the trailer, have the DW hit the switch to open the slide and push on the left side from inside to get it to pop open, after the pop, it goes just fine. Like I said, the bottom seems to start to go out just fine until the top left binds it up.
Any ideas ?

Thanks
  • Yes, did the same. Dry lithium on gears, I use 303 on the slide seals.
  • I use silicone slide seal lube and a dry spray lube for the rack and pinion underneath. Otherwise ours will get sticky in our hot humid air.
  • I have a Denali 5th wheel and had the same problem. Combination of the slide seal gasket deteriorating to the point it was sticking to the slide (check the upper edge of your slide at the trim for any black residue). Also, the slide skis (the plastic edges on the bottom of the slide that slide on the roller when slide moves) were cracked, so may have been jamming. Check yours to see if they are cracked along the edge where they bend under the slide. If they are, you also have water leaking into the slide floor. Replaced slide skis last weekend, did the seal gaskets today, we’ll see if that takes care of the problem.

    Spring in your slide topper is hanging up the pop is it unhanging


    No slide topper.
  • Just took a trip back to your area and the humidity made our seals stick to the slide out. Baby powder helped a lot. Hope that's all you need to do.
  • I don’t know if it would affect the operation of the slide or not, but I will mention that I ripped out the sofa and dinette 2 yrs ago. This trip there is a futon and large dog crate in the slide. It did show signs of mild sticking last season, but I though it just might be the seal.
