Is it normal for some amount of slow leaking on the airbags? I put mine on new a couple mos. ago and loose about 10 lbs a week or so.

I have never had any but I would think they should not. If your tire was doing that you would know you have a problem.

The Frieghtliner we have here on the ranch will lose the air out of the air bags in a few days, but it has over a million miles and we do not treat it very well. I would get spray bottle like an old windex bottle and put soapy water in it. If there are any leaks in the air system, even a small one it should be noticeable with the soapy water, but I would not think that a newer system should be leaking air out of it.

Yes, you guys got to be right. Should not be any leaks. I sprayed them before with soap and water and nothing showed up. I think if I use something with less bubbles to begin with I might find it. Something like wd40 might even give a clue where it is.

are these inflated by valve stem or by onboard air? if it is valve. stem it could be leaking.

It's a remote valve stem on the lic plate frame. You could be right, I never sprayed the actual valves. Thanks everyone... I'll report back this saturday when I get a chance.
