Hi Walt, Let's start with a few questions about the airide.
So there are no Mfgs. names on any of the suspension components??
That would lead me to belive that it is not a factory installed system, Most likely aftermarket.
Is there any controls or a dump valve in the cab of the truck??
After the truck sits without the motor running for a few days do the airbags loose pressure??
Have you push or pulled by hand on the valve linkage that is located on the rear??
How long have you had the truck?? & Did it ever have a smooth ride??
What is the height differance between deflated and inflated airbags??
This is a start.
Regards,
Marc
