Air

Driving down highway we are getting a puff of air from the eight front about every 1/8 mile. Any ideas? 2008 American Eagle, Spartan chassis.

A puff of air that you feel? A puff that you hear? Where on the right front is it coming from? The wheel well, the dashboard, the HVAC vents, the door?

He stated the "Eight" front, not "right" front.

I assumed it was a typo, but maybe it is, indeed, eight something.

It is a puff of air on the right front. Sorry for the typo. DW thinks it is the brakes, I am leaning towards suspension as there is no rhyme to it. On rough pavement it does it. Looked at the RF bag, but there are no holes/cracks. Does not do it when standing still. Is there some sort of valve in that area? Do not want to go to a Spartan shop.

Any advice what to look at.

The ride control valves for the front axle are up there.

If the MH bounds UP, the valve will dump some air. If the MH sinks, air is added. Its attempting to keep the MH at ride height.

My 2008 Dutchstar on a Spartan chassis does the same thing. I can hear the air escaping from the front suspension when I go over large bumps or around corners. I thought at first I had an air leak but when I drive in a straight stretch with few bumps, the air doesn't leak out. And I keep an eye on the gauges. I guess everything is ok...I hope.

It's either your ride height valve on the right front or the air dryer which is normally mounted in the center rear of the coach. If the air dryer is dumping that frequently, you have a leak somewhere. You can test the air dryer by running the engine and just sitting in your driveway. It should be pretty infrequent.

If your ride height valve has a leak, you will hear air escaping from it after you shut the engine down.
