Noisy slide

[Tov61]

Mt bedroom slide is becoming noisy when sliding in and out. I read somewhere that lubricating the bottom of the extended slide helps to preserve the slide blocks. Anyone have experience with this? Thanks for your help. 2003 Dolphin 6320 LX.

Have you pulled up the bed and looked for the mechanism? Or pulled out a drawer under the bed and looked around ? Wax under the slide/rails ?

My coach is a 2007 Dolphin 3220 LX. Just after I bought it, used, My bedroom slide emitted a loud bang, and ceased to function. Raising the bed, I discovered the gear box on the slide motor had exploded, throwing metal pieces everywhere. The reason turned out to be two. First, the back mounting bolt for the slide frame was directly over the heater/air conditioner vent (basement ac) and was unattached. Second, the other mounting bolts had loosened, all allowing the frame to twist, adding extra force to the gear. I had to replace the entire motor and gear, as the gear was not sold separately. I drilled an additional mounting hole through the slide frame and the bottom of the RV, close to the open, unused hole. I pulled each bolt, applied blue Loktite to each one, and tightened each securely. So far, so good! Now I occasionally check ALL my slide bolts for tightness. Good luck!

Yup, same on my National #6355. I got a can of WD slid out spray and stuck the small diameter tub, that goes in the spray nozzle, and stuck it through the rubber at the bottom of the slid where you see the roller marks. That helped, so next I used white spray grease with the small tube. I really used a lot of both of them. It cut down the squeal about 80%.

This has got to be the worse deign ever for a slide. Probably the only place National went real cheap. The bed just slides on the metal frame and nylon glides or at least it does in my LX 8360. If you are like most of us you utilize the under bed storage to its fullest capacity and that is where the problem lies. The design just can't take the weight. What they should have done was installed rollers like they did on the lounge slide then it would have been much better. Not sure what the solution is as I have tried to lubricate it and it does not last long. Still have not figured out how I could put rollers on it without removing the slide.

I read to use wax on the bottom of the slide! I used a candle and rubbed it on the bottom and it helped immensely.

Is the noise from the RUBBER SEALS, OR THE FLOOR ROLLERS? If rollers, better inspect for lost diamonds and socks/ sand/ gravel with flashlight and mirror or cell camera??

Hi everyone from the cold mountains of NC. Ours bedroom slide out is noisy too. It's kind of embarrassing to hear this thing slide in and out. I used the WD 40 slid out spray and it helped but not much. I got a can of the spray white grease and stuck the spray tube through the outside seals where the tracks can be seen underneath the slide when it out and sprayed a lot of grease in the tracks on both sides of each slide mark. I marked the location of the rollers and retracted the slid out and then sprayed more white grease between the slide rubber seals and the bottom of the slide out. It helped a lot. When the bed is lifted up, I can't see the rollers or whatever is used. It's not the best in design for a slid out.
