Bedroom slide

[JimdeVos]

The bedroom slide on our 2007 SeaBreeze LX 8311 was making a metal to metal squealing sound after sliding out one foot, then stopped squealing as it slid out further. As time went on, it squealed at several points; both when sliding out and sliding in.

I thought maybe one of the roller bearings that supports the room was going bad so took it out. The bearing (and the other 3 as well) was fine. Had a difficult time getting it back in because of the very tight fit between the threaded roller shaft and the hole it goes through in the support channel. Luckily I didn't mess up the thread and was able to nut it tight again. However, now the slide squeals louder and in more places than it did before!

There is no debris, the track gear is clean, the drive roller attached to the motor shaft is clean and not worn. The nylon glide pieces seem OK, but when the room is out, I can see some slight scrape marks in the direction of travel on the bottom of the room enclosure.

Is this maybe an alignment problem? If so, how do I go about re-aligning this bedroom slide? Any help would be much appreciated.

I do not know the brand of Gear Rack Slide Out. The literature the came with the RV has a RBW Industries, Inc pamphlet and also a APW Engineered Solutions Power Gear Division video that does not seem to match my slide. Again, thanks for any help you can provide.

Mine is a 2004, could be different.. I am not sure where your roller bearing are. Mine rides in nylon blocks. They were getting worn down close to the screw heads. Several on here recommended coating the "box" with Mothers Carnuba wax. It makes the whole box slide out easier.. I put it on thick with a sponge mop and donnt wipe it off or buff at all. Try it.

Thanks. I'll check the nylon blocks for screw heads rubbing. I've greased the tracks with a thin layer of marine bearing grease but with no improvement in the metal to metal scraping sound. After taking one of the rollers out and putting it back in, the sound is louder and it scapes in more places as the room slides in/out.

The room is mounted on a sturdy steel frame that slides on nylon blocks and is supported in the center by 4 rollers mounted in welded together back to back channels with a long straight gear bar welded to their bottom. it in turn is driven by a round 3"X1" gear mounted at the end of the motor gear box.

The welded channels and gear bar have 2 ea. 1/4" X approx. 4" long bolts at each of its ends that appear to be for alignment?? Haven't touched those afraid I'd get the whole room totally out of wack. Any suggestions anyone??
Thanks for any help with this.

Problem solved! At very bottom of bed are nylon support blocks that the support frame rides on. These were totally dry. lubed them and problem disappeared.

Jim, what did you lube them with? The bedroom slide in my 2008 Sea Breeze also squeals.
Thanks,
Alan.
