Ride height leveler leaks through exhaust port

I’ve replaced the leveling valve on my truck a couple times just to see the air bags flat the next morning.

The valve on my flatbed trailer will keep the air bags inflated for weeks with no air loss, but it is a different style valve too….

 

I go thru valves every now and then. Especially with air ride all the way around. They do allot of work. They go bad. Maybe TRP vs. OEM. I haven’t replaced the TRP ones yet..

 

Hmm funny I've been through two of the trip ones in like 6 months now

 

I took apart an old leveling valve that I pulled off a trailer and it had gunk and debris in it. I think the inside of the tanks can corrode and send tiny flakes into the valve, along with moisture and oil. They're pretty easy to clean and rebuild, though; just a couple of o-rings inside.

 

Did you check it with some good mechanics????

 

Have you played with the arm to see if there’s a spot where it stops leaking?
Quality control isn’t what it used to be.
