Roof vents bouncing when retracting.

[cm2785]

Hey guys, I just replaced the vent lids on my RV with new Camco’s (I also installed new Max Airs too!) but I noticed when retracting the vents now they start to bounce and make the roof resonate... it’s really annoying and I find myself having to put them down increadibly slow so it won’t happen. Nothing looks like it’s binding, I’m really curious as to why that would happen and what I could do to fix it.

Thanks!!

Mine do the same thing but I always had other issues to think about and fix they are now 21 years old and still shutter when closing. If you look at the attach point on the cover it is a very short moment arm.

Thanks guys but from what I can see the part that goes into the new cover (the metal crank arm) is metal with no bushing or anything. It’s metal to metal it seems.

You'll find the same thing happening with your antenna. I use a silicone spray on both. My antenna and roof vents all go smooth now. Do it once a year and you'll be happy.

Just lube the slide mechanism on them. Use something that will do a good job and stay slippery. Something wet is fine. Who cares if it attracts a little dust? Just wipe it away the next time you lube them.
However, I would be tempted to try a little wax like is used on ski's.

Try some olive oil. It won't attract too much dirt.

Almost all lubricants may be come contaminated with dust. Test anything on a blotter first. If you can see the residue--don't use it.

I have the same issue, just never thought anymore about it. I just looked at it and I think that it is caused by friction between the plastic bushing on the elevation rod and the track? that is attached to the vent cover it self.
Some sort of lubricant on the plastic/nylon and track might help.
