Title: MC5 Air suspension
Post by: Dreadnought on June 12, 2017, 09:36:55 AM
I started up my bus in the camp ground, as I do periodically. I've been running it regularly now, however this time, as the air suspension powered up- one corner - the front right, didn't pump up as much or as tall as it should. From the front poor Dreadnought looks like its keeling over slightly. All the other corners seemed normal. In the past when I powered up with a flat- even the side with the flat tyre charged to full normal height!

Any suggestions of how to trouble shoot this- what components to look at and if there are any specialists in the Elkhart area that youd trust?

Or would it mean driving back to my favourite mechanic in MN- with the bus keeling over?!

Cheers

Do you have the original automatic air suspension leveling valves? If so, you have one in front, two in back.
Or do you have manual valves?

I think they are the original.

How do I check?

Is there something I can take a picture of and post here to clarify?

As tom says, the rear axle sets both rear ride height, and levels the entire bus.  The front pair are connected together, air up as a single unit side to side, and only set front ride height.  You're probably just noticing a little difference in rear level that will go away once you move the bus.

I agree with Bryan - take the coach out for a drive (10-15 minutes) and see what happens.

FWIW & HTH. . .

Drive it. The suspension connections points will be bound sufficient that it doesn't readily jump to ride height.

You should hear what it sounds like when you air up after sitting down on the stops for the winter!!

Bang, creak, snap, bounce!

happy coaching!

Yea- it sounded pretty normal. I'd understand if the us was sitting for a while (as it was last year before I rejuvenated it spent thousands but I've been running her every one to two weeks. We'll see how it goes

Thanks everyone! I drove it today and it sorted itself out!

When I first powered up, it was keeling over again on that same side and for the first few moments of driving across town it did, but then it evened its way out.

Then I got a quote for interior work on my RV at a specialist and I almost keeled over!

 :) it's always a bit different when we forget the tooling and shop accommodations.
I suppose thats a big part why we are working ourselves on many of the task. Hell
I'd be real glad to just go birdogin for pros to do this stuff but alas the lottery ticket
Winning number still out there like a carrot.
