Ok, this is something I never heard before, till today, so I thought I would put it out there for validity?

Is it true that only ( One ) set ( side ) of the dual drive tires receives power from the differential? The other opposite set just turns freely? I was sure that in a rig this size they would have a posi-trac differential set up, so you got power from both sets of drive tires?

Is this a stupid question? Did everybody else no the answer to this?
