Your truck has a combination valve left front under the fan shroud. But if you are having a problem with 1 wheel on the rear axle,the problem is at the rear axle, I side is gummed up,frozen,blocked or not adjusted. There is only 1 line supplying the rear so if you had too much or too little pressure it would be at both wheels,not 1 wheel.
