Problem w/ Schwintek slide

[M/Sgt Blevins]

I have a 2017 front living Montana with the Schwintek system on the living room slides. My problem is that when retracting the curb side slide it gets half way in and it starts pulling the aluminum frame away from the body about 1 1/2" but just on the bottom right corner. When I extend the slide, it goes back to the correct position. Can any help with a solution? Thanks

when is the last time you lubed them?

I am not sure what you are referring to when you say "the frame".
I took a pic of mine (bedroom slide is Schwintek).
Which part is separating - A - B or C (or D none of those).

...or look at this exploded view of a Schwintek - actually this is a Lippert - but it looks just like a Schwintek (may be the same - I have no idea). Found this on line. I suspect that since so many parts on my Monte are Lippert - this may be the system that they use.

Yes, I have done the lubrication procedure several times but that didn't help.

The "frame" I am talking about is to the right of the letter "B" in your photo. It is the vertical piece that is attached to the body with screws. When retracting the slide the screws are pulled out along with the "frame"

Sonds like someing is binding and pulling the track away from the slide

As Jeffba said - it sounds like when you retract the slide - the slide box is getting hung up on something and stops moving. The motor keeps turning the gears in the bottom of the H-column...and the moving gears are "walking away" from the trailer body. Probably the H-column screws have pulled out of the stud.

You need to get down on the floor inside and watch the thing as it retracts, and also watch it from the outside to figure out why it binds up. If the screws holding the H-column have pulled out you will need to put in new/slightly bigger screws to make sure it stays.

It might help you understand how they work if you watched part of this video of the Montana factory and see how they are installed. At about the 17:00 mark in the video...

...you can see the factory guys lifting the smaller slides with Schwintek mechanisms into the sidewall slide openings. (screen shot below) It looks to me like the "H-column" (or what you are calling "the frame") are preinstalled on the sides of the slide boxes. They lift the boxes up into the opening and push them into the trailer. Then the guys screw the H-column to a stud inside the bonded wall unit. I marked up a screen shot with notes below.

Sounds familiar. We have a 2917 3790 RD. Last year I had the same thing happen. When the rear den swintec slide was drawn in the slide would tip down inside and push the bottom frame of the slide out about 2 inches. We were snowbirding in AZ so I had a mobile RV repair outfit check it out. They found almost all of the small sheetmetal screws olding the frame to the trailer were either sheared off or they had missed the aluminium stud. We were lucky the slide didn't fall out when taking a corner. They checked the other slides and found some others also sheared. They called the keystone and asked about a recall but there was none. Their thought was that the screws were self tapping so the factory did not drill holes but just used power drivers to screw through the slide frame, the fiberglass skin and into the aluminum stud over torqueing and cracking or shearing the screws. The fix was to drill a hole next to the sheared screws and add a new larger screw after jacking up the slide and lining the slide frame back to the side of the rv.
