Unlike Prevost, Newell does not lift the tag axle off the ground. The pressure on the tag axle can be decreased or increased (after about 1993) by a toggle switch on the dash. The increase in pressure transfers more weight to the tag and front axles to reduce the load on the drive axle to assist on getting through weigh-in-motion toll road scales. The decrease in pressure transfers more weight to the drive axle to help in situations where the drive tires are spinning, like wet grass. This switch should not be used for maneuvering.
Newells with the ZF suspension, have active steerable tag axles (#671, 681, 685, and all after 696).
An air leak in the rear can result in the outside drive tires rubbing on the fender. Bad for the tire. Potential locations for an air leak are the rear ride height valves, a leaking air bag, or a leak at the 6 pack for the rear suspension. Check all fitting for leaks. Newell uses push on fittings that are prone to leaks after a while.
