XC front air pressure question

smlranger · 09-09-2008, 02:56 PM

Hooking up the rig tonite for our trip to Yellowstone tomorrow and notice that my front air gauge is only reading about 75-80 psi vs. rear which stays at about 100. This is sitting still in a slight nose-down attitude and after a sufficient period of fast idle. I cannot hear any leaks under the rig when I shut it down but just wondering why the front air won't catch up with the rear. Would figure an issue to develop the night before leaving for a long trip

.

Any suggestions are appreciated.

I am not sure of the problem but I would level the coach with the auto leveler jacks and then stow them for travel. There might be a sticking valve. That is what I would do before calling a mechanic.

Good luck

guage is just stuck gary, don't sweat it. is the warning buzzer off, if so your cool. run it a while and see what happens. mine get goofy every once in a while too. but they always work.

I think Steve is right. I've had a low reading on the front gauge from time to time but it always resolves itself after being on the road for a litle while. As long as you are over the low air threshold you should be good to go. Has the coach been sitting for a while?

Even with a massive leak the compressor should be able to bring the air up to 125 psi with the engine running, even at idle. If it doesn't come up within about 5-7 minutes, I would suspect the gauge. That's assuming the suspension appears to be fully aired up.

Your brakes and such are fine at about 65 psi, so no worries there.
