Need some input; slide does not stay put

Just an older thread about the Lance travel locks used on some.
https://www.rv.net/forum/index.cfm/fuseaction/thread/tid/25403979.cfm

Ours locks ares simple 1" steel tubes with rubber feet placed between top of slide and wall. Looks like the same HJ mech. If I forget to use locks, our slide will open a bit but its noticeable in the mirrors.

Try this group, there is a couple more lances around there.

My 2012 Lance 855S has a slide made by Happijac. As previously mentioned it is the friction type. I have no idea if your slide is the same as the one I have.
But here is how mine is adjusted. There are two rails under the slide, one of the rails has the drive motor and one friction adjuster. The other rail has two adjusters. The adjusters are tightened or loosened for the desired effect. Look for two 3/8" nuts mounted on the outboard side of the rail that does not have the motor mounted to it. As Rick mentioned bring the slide in about half way, laying in the floor locate the two inside adjuster nuts and tighten about 1/2 turn. Then go to the motor driven rail and locate the one adjuster nut and tighten it same amount.
I use a 1/4" drive socket set, a 12" extension, a wobble fitting, and a 3/8" socket
Hope I didn't confuse you, after proof reading this I think I'm confused. lol Maybe this will help.
If you tighten it to much the slide will stop/go as you are moving it. Just loosen the nuts until it moves without cycling on/off.

Thanks for the replies so far. Its after dark so all I can do tonight is check the manual. Hopefully theres some help there. I found a sweitch in a cabinet that's labeled "slideout manual override. Its off. When I first took the camper out 8 years ago a plate slid into the switch changing the position. That stopped the slideout from operating.I don't think the the issue has anything to do with this swich this time. But there is a procdure sticker in the door that mentions travel locks. Never knew I had them or their location. Hopefully the manual helps. Its odd that I never had this issue in the 8 years Im using the camper, which is why I thought something might have broken.
I'll also check the rollers, thanks Rickjo.

Non-Lance owners have lots of free advice, but I don't think it helps in this case.

If it is a slide similar to my 2007 Lance 1181, full wall + fridge + closet, then the friction needs to be increased at each of the 4 support rollers. Access the inside ones while the slide is part way open, laying on your back on the floor. Access the rear outside one thru the upper side of the rear storage with the wing open (?). On mine the front outside one is accessed by removing the drawers under the closet. You will have to deduce where all your access points are. A socket wrench did the trick. Just tighten enough to prevent the roll out, not TOO tight, however, as the side has to move normally.

Mine used to creep out 2" or so on curvy mountain roads 'till I got the friction set correctly. Been three years or so since the problem has occurred but I adjusted several times before that.

I would add: Do you have slide locks? Usually they are adjustable poles that go above the slide wall (when in) and brace against the wall of the unit. This holds the slide in place while you are driving. If you don't, I strongly urge you to get two or three 1x2s and cut them 1/2" longer than the span between the wall and slide, when in. Slide them in to the wall and then tight against the inside of the slide in the front, middle and rear. The slide locks are available at a dealer and should have come with your unit.

FWIW, the slide on my previous 08 Arctic Fox had a lock that was accessed from a little door on the outside rear of the camper. The first 4 years I owned the camper, it wasn't necessary to lock the slide to keep it tight. After about the 4 year mark, my slide would begin to creep out while driving. It wasn't off track, bent, or missing any teeth. It just crept out about an inch or two while on the road. I started locking it from then on, and no more problems. I think most slides have a locking feature. Good luck, Brad

Did you travel with the pass thru open and others closed?

Assuming your slide is hydraulic:

First thing to check is the reservoir to ensure it's full.

If it is, then the next step is the solenoid itself. May need to replace it.

Finally, it comes down to the motor assembly.

Start with the easy stuff and move to the more expensive....Dennis
