Dolphin bedroom slide is noisy

[kokpelli]

When moving slide in or out there is a scraping noise. This is a 2003
Dolphin 35' with a side by side bed and closet. A former National RV dealer suggested a paticular slide lubricant which made the noise worse. I have also waxed the bottom of the slide which moves over teflon blocks. It is just as noisy empty as loaded. Has anyone else had this problem? Movement is smooth.

Others are saying, clean up the working surfaces and coat them with carnauba wax. Mine was squeaking, it had not been used for over a year before I purchased the motorhome... but now after lots of use it stopped squeaking. Putting carnauba wax on the slide is on my list of things to do.

You can also wax the sides of the slide room, clean the seals and condition them with Protectall seal conditioner. Also under the bed everything that moves, slides or rotates give a good cleaning and spray with silicone spray.

I full agree on the Carnuba and cleaning the seals. it helped mine.. The dealer shop wanted $2200 to replace the teflon blocks. you might look at the blocks to be sure they are not warn down to the screw heads.. Lots of Carnuba applied with a cheap sponge mop then spray silicon w/teflon.. let us know how it works out

Here is something that is taken for granted. You put the carnauba wax on the outside of the slide out when the bed is out. If you look under the slide-out when the bed is out, you will see marks where the slide-out slides over the three teflon runners. Move the rubber seal and you can see the telfon slide blocks. Where the marks are on the bottom of the bed slide-out is where you put the carnuabe wax. I did this and there was a dramatic difference. You can also put the wax on the other end of the slide where the front teflon blocks hit. This has to be done when the bed is in.
This took a while for my pea brain to understand because I didn't relize that you apply the wax to the underside of the outside sliding room. There weren't any marks and I couldn't see the outside teflon blocks so I really didn't know what everyone meant by waxing the slides.
Hope this helps. It really cut down my noise.

One of the things that I have found out about the bedroom slide [after lots of work] is to sand the areas that slide over the nylon blocks with 600-800 grit wet sand paper. This will create very small scratches that will hold the wax. Carnuba wax [not the new hi tech stuff] will help the slide work more smoothly, but waxing AFTER sanding will make an AMAZING difference in the way the slide moves. Make sure that the sand paper is wet before you sand the areas [only the areas that slide over the nylon blocks]. I know this will make you happy. Make sure not to use ANY lubricants in the areas that you sand and wax. Using lubricants of any kind will make the slide shudder as it moves in or out.
