When airbags are empty the right side of a dryvan trailer Lean on to of the tires. What can it be? Yes it’s loaded my my other dryvan not doing that. I changed the airbags. And didn’t fix it I put a picture of the other side. That is working properly. Thanks

Need to know what suspension you have. If it’s a Hendrickson, I would look at the pivot bushings.

Yeah it’s a Hendrickson . Would a bad bushings make the trailer rest on the tires ?
-
Is there an air dump valve on it? Did you check the leveling valve?

when the bags are up it gives me around 1 inche on that bad side . When bags are Down it rest on top of the tires .

Pretty sure it's the pivot bushings on that side

Looks like two new air bags on one side. The base looks different,is that the side it’s leaning towards?
Rideandrepair and Vampire Thank this. -
You have mismatched air bags. The left side has a flare base, the right side is a straight base.
According to Hendrickson you cannot mix flare base with straight base air bags as it will give you different ride heights.
You’ll need to choose either all straight base or all flare base, because they’re incompatible if they’re mixed.
Replace the air bags with the base the came on your trailer originally from the factory and your ride height should return to normal.Rideandrepair, Siinman and Accidental Trucker Thank this. -
Yeah it was the airbags the plastic base was shorter. I didn’t know the trailer rest on those plastics things
