Suspension question

[ronmarabito2002]

've noticed lately that when I lift or deflate my tag axle suspension, the back
end of the coach is down. The drive axle bags used to support the rear end when
I did this. When the tag is re-inflated the rear end comes up just fine. Is it
likely that it is just an adjustment issue or do I have bad bags?

Ron,

The tag axle holds about 10,000 pounds with about 65 pounds of air so you should get some weight transfer to the drive axle when the tag dumps. If you think rear istoo low, you can check the drive axle tire pressures first, then find a safe place to check the drive axle air springs and the height adjustment valves. If you tap on the inflated air springs (bags) they should feel like a tight drum if they are up to pressure.

I am planning to change all 10 of my air springs (91 WLWB) this fall since they are now 20 years old. (Before I get too old to do it myself!). I also have a pressure protection valve in between two junction blocks (with about 4 airlines each and above the air dryer!)that has a leak in the diaphram cover that I want to replace also. I'm deaf as a post so isolating the air leaks with the hearing aids up full blast is a task! Lots of spraying soapy water.

Thanks Bob. It will have to wait till I go down to Blanco for a show. Might
have it looked at while I am down there.
