Suspension lowering after a couple of days while parked

[mckyver]

Has anyone had this problem , i have a 2018 Berkshire XL , and after being stationnary for a cople of days my suspension lowered itself .
Also once i have started the RV and gave it time to re level the suspension , the rh frt is not as high as the left hand side can barely pass my
fist between tire and wheel opening.

Any ideas ??

Thanks

Mike

I believe leak down in a couple days is normal. Mine does and previous discussions here have shown that others do also.

As far as the front being out of level, you may need the ride height adjusted. Do you know if it is still out of level after being driven?

FYI I had mine adjusted the first time under warranty at no cost.

Freightliner's factory center in Gaffney SC can easily handle your adjustment - but, of course, any Freightliner facility should be able to as well.

I find that my coach will also lose it's bag air the longer it sits, with the bags left inflated when parked, and no legs down. Of course, when we park with the legs down, we deflate the bags beforehand anyway, if not automatically - our coach allows either way.

Before you go and try to bring it in for service, try this:
air the coach down but don't let the jacks go down all the way. Restart and let the coach air up.
Shut down, retract all jacks and restart. let the coach run for a while and see if that gets you back to normal.

That works if the suspension is not getting ANY air.... it's ONE valve into the system. If there's air, there's air to all of it.

Meanwhile to the OP.... I would drive it first, and then come to a nice straight stop on level ground (say a Wallymart parking lot) and see if you're REALLY out of level.....

As for the science here.... there are THREE ride height valves... IIRC two on the front and one on the rear or vice versa..The axle is connected to them with rods and the valve either lets air in or out of the bag depending on height. Get under there and find them and see if there are any obvious problems with the rods as they are somewhat delicate little things... Do an image search for: https://www.google.com/search?q=rv+r...w=1429&bih=766 and you'll see a bunch of different ones to give you an idea of what you're looking for.

If one is in fact out, they are not hard to adjust. Get the distances from FL, it's down to the 1/2-1/4"

Ok will try and give you feed back.

Two on front, one on back. This is what they look like.

When you find them it doesn’t hurt to give then the soap test just in case the valve is going bad or leaky connection. I’ve had to replace two, both passenger side front.

Not sure what you mean by complete system, but I did have both of my adjusters replaced within the 1st 6 months.

Glad you're back in business.
