Slide out uneven.

[theflandersons]

Hello all.
I have a 2020 Jayco White Hawk 32 RL. We bought it used last Spring and have been doing some maintenance on it.
I replaced the wiper seal on the passenger side slide-out however the seal is not sealing properly when the slide is extended. It's as of the slide out is sitting higher on the back corner closest to the coach. I confirmed this by using a small piece of wood as a measuring device. The gap between the slide and coach is much bigger (half inch..ish) at the top than at the bottom. I have attached pictures. I can not see anything under the slide that could be wedging it up like that and am now at a loss as to what is happening.
The slide sits perfect when retracted in the coach.
I appreciate any and all help!

Your slide out needs adjusting obviously You need to know what type of slide you have then search u-tube videos for how to adjust your slide. I've done this myself to see how to adjust my slide-out...it hangs low/not level when extended. Looks easy enough to do...the hard part is getting down there then up again I'm going to tackle it in the spring.
Yours looks more like a vertical/plumb adjustment which can be done

Thanks for the reply. I have done the youtube thing and searched forums. I have been able to adjust the slide in every manner except the vertical tilt side to side as shown. When retracted 2 inches in or more, it perfectly level. Only tilts like that once fully extended. I have looked under the slide to see if there is something it's sitting on but can not see anything out of the ordinary.

Wild guess. You say the slide is plumb when retracted a few inches, but goes out of plumb when fully extended. With most slides, as they extend beyond the halfway point, the outer wall side sags until it fully engages with the main cabin sidewall. The the flange on the slide and the structure in the sidewall opening meet, first at the top, and then as you continue, the bottom of the flange eventually seats against the base of the sidewall. A kind of levering action.

With that in mind, PERHAPS the slide mechanism itself is loose at its rear-most connection, and when the slide flange begins to engage with the structure of the main cabin sidewall, something in the slide mechanism gives and lifts that side as the slide finally fully engages with the main cabin sidewall. That might make it behave as if it's climbing onto a wedge in those last few inches of travel.

I have a rack and pinion slide. Were this to happen with my slide, the gears in the rack and pinion mechanism would disengage and chatter. So I venture that, if this is the problem, you don't have a rack and pinion slide. It's obviously not a Schwintek. Is yours hydraulic? If so, each end of the ram would typically be connected to the framework using a heavy steel pin retained by a clevis pin. This hitch pin illustrates the concept. There are all manner of "hitch pins" that might be used. BUT, if the clevis pin fell out and the hitch pin were partially backed out of the connection between the hydraulic ram and the main framing on the "inside" end of the ram, when you reach full extension, the ram might want to climb out of its connection with the frame and thus lift that side of the slide. (BTW, the retaining pin could be held by something like a Circlip or even a push nut (the kinds of retainers constantly falling of your awning hinge pins.) The pins on the slide would be more robust than the hinge pins on your awning, but nothing as stout as the hitch pin in my illustration.

As I said, a very wild guess...and only if it's a hydraulic slide. Other slide mechanisms might cause the same problem in a different way. If it's anything like this, you may be on the precipice of a catastrophic failure if something in the slide breaks loose. You are just in time to fix it if this is the problem.

Thank you for the reply and suggestions!. I was under there today and it is a through frame mechanism. I inspected all along the seal underneath between the coach and the slide when fully extended. There is nothing binding or stuck underneath causing the tilt. Inside, the floor of the slide appears to be sitting properly on the floor of the coach with no gaps. I can jack up the inside corner of the opposite side and get the slide even, but that creates a 1/4 inch gap inside the coach at the floor.
Is it possible that hole in the coach for the slide could be crooked?? Or the slide itself? Is this something that has been documented before?

Also, I did inspect all connection points of the slide mechanism and all is tight and accounted for.

Use a framing square to tell you what is and is square.

Hello all.

Did you ever straighten the problem out.

I see what you did there!! Very good.

I have not yet. We have had a bit of bad weather coupled with work has left me with precious little time . My plan is to go this weekend with a square and try to determine if the issue is with the slideout itself is not square or possibly the hole within which it slides in and out of. I can't imagine they would be though as I would think they are framed on a jig.This is difficult as, short of removing the seals, it's hard to get consistent measurements to anything. These trailers are built so fast precise measurements to trim etc. is unreliable.
I have wondered though if the slideout box is out of square and has shifted and I am hoping loosening the brackets on the outermost wall and attempting to do a horizontal adjustment could make then difference. I am skeptical that is the case though based on how uneven the slide is in the verticle plane as in the picture.
I will post all pictures and results from my work this coming weekend.

I'm going to check mine today I'll keep in touch.

I was at tne trailer today and took some pictures and measurements. It seems like the bottom of the slide needs to be bumped towards the front of the coach a bit to get it even. It's a big slide and doing so will be challenging. I tried today and couldn't even budge it. If anybody has any tips that would be great.
Here is my plan:
1. Get even in the horizontal plane. I know how to loosen it just can't physically move it.
2. Re-measure and see what the vertical looks like.

If you look at the pictures I just posted, when I measure from the roof of my slideout to the frame of the hole, it is very close and doesn't seem off enough to cause the discrepancy noted in the original photos. Perhaps the horizontal adjustment will be enough to tweak it?
Any thoughts are much appreciated.

In the photos front means towards the hitch and rear means towards the bumper.
