I am not sure of the pressures or height that is required. I am breaking spring a bit too soon like every year. Help. </div></div>The height settings are all different.We set them them with the Factory Height Gauge Pete requires us to use.The Settings all vary it will depend on what style Ride set-up you have.Its either Air Trac,Low-Air leaf,Or Flex-Air. More than likely it is Air Trac.Your leveling valve may also be Bad and Not working right.Basically it is the Driveline angle that is most critical when setting ride height.You can set it close by looking at the angle of the short-shaft between the rear drives.Putting it simple You want the yokes on a even plane so to speak.Looking at the shortshaft from under the tk it should be at a slight even Incline with the output yoke on the front rear even with the Input yoke on the rear rear,If it is a single axle which it probabley is being a 330 just observe the angle of the end of the driveshaft yoke to the Input yoke on the rear same rule applies"You want a Even angle"This is the safest way to set it without the proper gauge and will get you in the ballpark,just jacking it up to what you think "Looks Good" can cause driveline damage and a pile of other issues..To check the leveling valve dump the suspension while parked switch it back on and see if it raises to the previous height.Also when you load the trailer or truck down does it compensate?.It only takes 10 minutes to check it with the Proper gauge.All dealerships will have one take it there and have them check it if you want it done right to Fact spec. which I would suggest you do.
