I have been having some problems with my slideout nylon supports. They seem to crack and break off. Winnebago replaced some of them when we were at the factory. I called HWH and they said they had a new style that might work better. They sent replacements. The new ones are black versus the white original nylon pads. I took some photos while I did the replacement. I replaced 8 nylon pads. My coach has 2 large slides with 2 main supports fore and aft on each slide. Each lower support has 2 nylon guides. I think the 2008 models have a solid guide which would probably eliminate this problem.

Here is an image of the parts that are failing.



My left slide has a backing plate that needs to be removed to access the upper nylon support. Removing the 4, 1/4 inch bolts and nuts was fairly easy.



Once the backing plate was removed I removed the 5/16th inch bolt which allowed the nylon bushings to be removed.



Once the upper nylon bushings are removed the slide support can be jacked up to allow access to remove the lower (problem) bushings.



After the slide support is jacked up about 3/4 of an inch the lower nylon bushings can be popped out using a small pick.



It is a little hard to see but this image shows the new black nylon bushings installed.



After this everything goes back together as it was removed.

I used a small bottle jack and a modified hand rail 4x4 to lift the slide support.



I did not dream this method up but it was given to me by Winnebago and HWH although neither would put it in writing.

Here is a picture of the broken nylon bushings and the new bushings supplied by HWH.



This took me about an hour to replace 8 bushings. I am sure not everyone who has this issue would want to tackle this themselves. Extreme caution should be used anytime a jack is being used. This is not intended to be a replacement for bringing the coach to a shop but just to show how I did the repair.

Well done. Thanks for the information. I'm sure I'll be searching for this thread in the future. Thanks again.

First, thanks for the great pics and info. Very helpful. Second, now that you have seen both the old and new, can you tell if the new looks any stronger or will hold up anybetter? There must be a reason why they changed to the black ones. Maybe stronger, different composite?

Outstanding information...very nice summary of your procedure.

I hold my breath every time I move the big slide, wondering if/when those nylon bushings will snap. So far, so good.

Thanks all for the comments.

HWH told me they were trying a new compound. As to if they really are using a different compound or just a different color so they don't stand out when they are broken is a different story I am teasing and think they are trying something different as they most likely know there is an issue with what they have been using. Only time will tell.

HWH has treated us like we were their only customer just as Winnebago has. Their support is appreciated.

The new black nylon bushings were a tad bit thicker other than that no visible difference.

I replaced my bottom ones. On the 34 journey they are similair.I beleive that when that slide is out there is alot of weight on the bottom part of the square tubing at the end that tubing bow down. If the end of the tubing had a heavier steel around the end of that tubing it would give it strength to keep the bow out and stop the guides from breaking. The white pads are to hard and can not take that bowing action. At lease that is what I come up with, being a x - steel fabricater. If you think about it, at lease mine and the ones I seen break in half.From one side to the other. You got to bend it, to break it.

Did you replace with black or white nylons?

The 2008 models without the storemor no longer need the split nylon support. They now have a solid nylon and steel across the face of the support. I would think that would eliminate the problem entirely.

I replaced it with the white. I guest the black must have just came out. I know that the nexts one i replace I will have made with better materail. If they are biffening up then the bowing was a problem.

RKL...My slides were all the way out. It would have been to difficult to do the repair with the slides in or even slightly retracted.

jimandsue60 - was very interested in your pictures and replacement procedure as I just noticed one of the nylon slides on my 2004 Meridian looks like it has partially broken and started to turn sideways. Are the nylons slides held in place on a metal post, couldn't tell for sure from the picture what they are attached to? Also, was the bolt holding the upper nylon block in place very visible or was it covered with something? On mine it almost looks like just a nylon post or plug extending upward thru a hole in the metal case is all that holds the upper block in place. I may have to hunt up a Winnebago shop to work on mine, which I will hate like the plague. You never know what to expect from them. The worst part is, I was just at Forest City last spring and I could have had all this done then had I known then what I know now.
