05 Volvo Setting air height on entire truck

I have an 05 volvo VNL.

I know a lot have talked about this in different forums but i am not sure if it changes by year of the truck and i have not see them all in one spot and some contradict each other.

I changes my tires to taller tires and switched all my air bags and ride height valves.

So how do i reset the rear ride height, front axle ride height and cab height? I have read volvo has a different procedure then most semi trucks so i want to make sure i get solid info using my truck year and make.

 

After contacting more shops then i can count i was told

-ride height for the front does not matter ride preference.
-cab is very specific but he had no detail only the bar coming off the value should be about 90 degrees?
- rear is based off frame rail size will post when i get it

How does this sound to everyone? The front has no set height does not sound right?

 

Yes!!! Thanks you. Anything like that in your book for the cab height?

Thanks again!

 

Thank you everyone that helps so much!!
