Air Bags

[sodbuster]

I have a kw t800 with 8 air bags, and gauges to monitor the pressure on the left and right side. I have noticed that the right side always has about 30 psi more air than the left side. I have measured the height of the rear frame rails and they seem to be the same height. I don’t like seeing the right side having 80 psi on the bags and the left only having 50 psi. Is this something I should address. Also when I am unloaded the left bags have no air and the right side has 30 psi.

sounds like the gauge might be bad

Some KW 8 bag has right and left leveling valves. I would look into replacing them. Sounds like the left valve is bad.

i agree with ptd, it has a levelling valve on each side of the chassis... replace both

the gauges are easy enough to check with regulated shop air
