[Fulltiming]

Newell uses ZF Active Steer Tag which uses a hydraulic piston to steer the tag axle. By contrast, the ZF Passive Steer Tag just steers as it follows the drive axle to prevent scuffing the tires. Just turning the steering wheel without actually turning, as likely shown in the photo, will not cause the Passive Steer Tag to move at all while the ZF Active Steer Tag would result in the tag axle changing steering angle under the same circumstance.

I have not been able to find any information on the maximum degree of cut for either the Active or the Passive.
