It could be many different things. If you are running the front off just one raise and one dump valve. You could check if the bags are the same height when the trucks layed out. The bag brackets could be a little uneven. Or if you have alot more air line running to one side than the other, or if there are different size fittings on each side could cause it also. If the truck has a seperate raise valve for each corner, one valve could simply be sticking when you raise it up. There could be alot of moisture in the valve and airlines.
