Tag axle - Confirm that the air pressure regulator for the tag axle is set at 25 PSI. The regulator is located on the forward, curb side wall of the engine compartment. Next, operate the three-position tag axle switch on the instrument panel. The center position is normal travel, pushing on the up side adds air to the tag, taking weight off of the drive axle, and pushing on the down side exhausts air from the tag axle to increase traction or shorten the turning radius. If operating correctly, you will hear air exhausting at the regulator when you push the switch on the down side. You may need to replace one or more of the valves. We recommend these valves be replaced every three years.
