Slide jerking

After the spring wash and wax and some interior cleanup I thought I would lube the slide seals. I even climbed on the roof and hung upside down spraying the top seal. I may have sprayed them 3 or 4 times in the past 2 years. I have cable operated slides. No toppers. I had the slides out for some interior cleanup and decided to put them in today. The bedroom and dinette slides worked fine. The kitchen slide (stove, oven, refer, & TV) jerked a good bit coming in. So I put it back out and it jerked again going out and back in.
I got the DW to operate the switch while I looked underneath while being operated. They were short little 1 inch jerks with a flapping rattling noise. I sprayed some more lube on the bottom seal and the bottom of the slide with no improvement. I need to look some more but I thought I would just post and get some ideas as well. Used "search" and didn't find much.
edit: I went back to the 5th and looked it over again before the rain gets here. Operated the slide, same thing. The cables appear snug and not jumping around. Motor sounds consistent. The rattling noise is on bottom. Looking underneath from the outside I can't see anything, no rollers, etc. Can't see anything underneath from inside unless I take the bottom trim off. I sprayed some more Protectall seal lube on the seals and the floor from the exterior and the sidewalls as well. No difference. Climbed up the ladder to look at the slide roof...no dead cat or anything. And...I was hooked to 110 volts.
I'm thinking I shoulda left well enough alone. Maybe the seals are too slick! Dang if I'll try to do right again! Just drive it like you stole it.
Naaaa.

The slide floor should ride on a block or full length of plastic/silicone. Maybe you need to check them. Retract the slide about 3 inches and you should be able to inspect.

Inspect from outside?

My second session of Googling "jerking RV slides" produced a post on **.net that a dealer advised to clean the slide seals with 409 and water on the same 5th, same issue. Another Laredo owner had the same issue, waited 3-5 days, all is well.
Waiting is what I do best.

Laying on the floor inside the trailer. You may need to lift the leading edge carpet if it has it, and use a flashlight.

It is all vinyl. If the weather permits tomorrow I will spray with 409 and spritz it with water. Maybe it's too slick, but I can't imagine what issue that would cause. I'll dig more.

could be the gear box on the cable slide motor. I had two fail me and had them replaced by the dealer, out of warranty of course, this is a BAL Norco slide system on a 2014 Raptor 332ts. I think the gears are nylon and prone to strip.

Hopefully not. Motor assembly sounds and looks good during operation.
It's just such a coincidence that this occurred after I diligently sprayed the seals, exterior walls and exterior floors with Protect All slide seal lube. All I can think is it is so slick that the entire slide is jumping ahead of the motor.
The other issue is the conversation on another forum with the same 5th as mine that did the same thing after spraying the seals. His dealer said to clean with 409 and water. A Laredo owner there had the same thing happen. I couldn't find any 409 this morning so I diluted some Super Clean and cleaned the seals and walls with that. Spritzed it all down with tap water. Left the 2 big slides out. Weatherman is saying they will get a good rinsing this week.

I fought same problem for months. Called Bal K & L manufacture tec rep. Issue was twofold. First, used a slide lube other than Slideout Rubber Seal Treatment by Protectal, Inc. made in USA (follow directions on can). Had to wash sides and rubbers thoroughly, but jumping still existed. Do not remove rubber seal flap at bottom - does not allow access to anything. Run slide fully out. Thoroughly wash black plastic bottom of slide. Purchase Zap or newly available WD40 Specialist Dirt and Dust Resistant Dry Lube PTFE spray (found mine at Home Depot). Soak bottom black plastic of slide. Run in and out a few times. Resoak. Run in and out. Should improve. Mine was so bad I had to get more aggressive. Ran slide 90% out, balanced on two large blocks and jacked up. Moved entire slide room up about 4". Reached in and cleaned hard rubber "solid rubber roll edge" (not a roller) thoroughly soaked with lube. Problem solved. Ours was so bad one of the cables jumped the roller. Be sure to check all cables and rollers. You will have to take the side plates off to do this (from the interior). Ours works perfectly now. Good luck. It is annoying when these things happen. We were on an extended trip at the time.

Edit: Positive note: Now have a real good working knowledge of our slide.

^^^Great info. Thanks.
What did you wash with?
Where did you support the bottom of the slide when you jacked it up?
Are you saying to use the Protect All, or not use it?
Is Zap a lubricant like the WD40?
This is crazy. My slide bottom and sides are clean and slicker than snot. I wonder what is different about the Protect All slide lube I used and WD40?? I was trusting the Protect All name. Was.

Use Rubberseal by Protectal, but only on sides and top. I used another brand when my problems began. Couldn't find the Zap lubricant that Bal recommended, so I got on line and was given the "special" WD40 called Specialist Dirt and Dust Resistant Dry Lube PTFE Spray - it's in a yellow, black, silver can. I cleaned the black plastic bottom with acetone. It was slick, didn't look dirty, but rag did have grease. I lifted the slide room with a long wood plank and placed hydraulic jacks on each edge of the room. Took two or three attempts to get it exactly centered where the room would balance and move up equally. That's why I used a wider plank. Had raised it about 3 inches. It looked like it could raise almost 6. I observed the top gap as I raised it. It was high enough that I could get my hand with a stiff rag and acetone to clean the black tube roll slide surface. First in and out saw definite improvement. Soaked it down with WD40. Next one better still. Third time, problem solved. If I see mud or dirt build-up now, I wipe clean with a rag and add a little WD40. I stress, my side looked clean to me, but the groove on the inside must have been where the problem really was. It was soaking down with WD40 and going in and out that finally lubricated the glide path that can't be seen.

Thanks a lot, excellent info.
This really confounds me. My slides and seals weren't particularly dirty at all. I used the Protect All slide and seal lube, foamy, made in USA. I'll clean it with acetone and maybe jack it up. Did you have the slide extended when you lifted it? For whatever reason that gives me the heebie-jeebies. The cables won't jump off the pulleys? I've got about 3 weeks before a long vacation, don't want to get into major issues this close to lift off.
I found the WD40 on Amazon.,but no Prime. If it ever stops flooding I'll venture to Home Depot or Lowe's.
Thanks again.

The lady from Bal had told me to only jack up as a last resort. We had started jerking before we left on a very long (7 week) trip, so I took it to a dealer, they worked on it and claimed it had been fixed. We left on our trip but the jerking continued. It finally got so bad that we took it to a dealer in Burlington, WA, they looked at the tune of $200 to tell us that it HAD jumped the pully and that they wouldn't be able to fix it for two weeks $1200, and we were leaving the next day. I ended up putting it back on the pully myself, we limped home, and that's when I spoke with the Bal people, and they gave me the advice I have given you, which solved a 2 month problem caused by using bad rubber seal spray in the first place. Go ahead and try everything else before jacking it up. I was just so fed up that I finally got aggressive. The jacking up was a scarey prospect!

Thanks again for all the info.

If you're going to use acetone to clean the underside of your slide, make sure that you don't have the plastic "slide strips" on the floor under your slide. Acetone may "eat" the plastic !!! I'm not sure if Montana HC uses the same "friction strips" as Cougar, but if they do, they'll be plastic !!!

Caution !!!

Have you tried applying baby powder to the slide seals? There are several suggestions for its use. Google baby powder for RV slides and check to see if you think it would help. I dont think it would hurt.

HOT DANG.....it works. I cleaned the bottom of the kitchen slide with acetone on a microfiber cloth. I didn't overdo it, just a few tablespoons on say a 3"x3" portion of the folded cloth. Cleaned the outside vertical seals and went inside and cleaned the inside vertical seals. Then wiped down the exterior side walls. I noticed the cloth dragging on the sidewalls and found some chalky residue on the cloth. Then sprayed the exterior floor bottom with the WD40 Specialist PTFE and the seals inside and out. I tried the slide and it seemed a bit better. I could pull the little exterior floor seal down and push the spray tube in there. Sprayed some more everywhere, slide got better. Sprayed the whole dang can. I'd say it is 90% better.
The seals definitely have a different look. They are shiny and not near as slick.
I still wonder if the ProtectAll didn't make them too slick.
Further info....you cannot see any of the underside of the slide from inside or outside. My other 2 slides the rollers are visible. Not this one. Chuckster and koko were on it. The bottom of the slide is slick...nothing on it.
I'll check on it tomorrow and hopefully it is good. But I do have another can of the WD40!
Thanks a lot folks. Saved my behind.

Sure does. Thanks for all the help.
But...did you use the WD40 on the seals? I looked at the seals again and they were shiny and sticky. I got the acetone back out and wiped the interior and exterior seals.
Not sure if it would have made any difference but I think all is well.

No. Don't use the WD40 on the side seals. Use the Rubberseal by Protectal. Happy camping.

It cleaned off pretty good! lol
I've put nothing on the seals since I cleaned the WD40 off. I'll hit them with the Protect All and probably some more WD40 behind the slide floor seal.
