So I have the van jacked up in the front the other night trying to figure out a noise. I noticed that when the car is in P, and I rotate the tires either forwards/backwards the opposite side tires turn in the opposite direction. That's normal right? Well, once I put the car in gear (any) and I spin the driver side tire, I get the same thing. However, when I spin the passenger side tire, I only get the opposite tire to spin when I go in reverse. When I go forwards on the pass. Side tire, my driver side tire doesn't spin at all. Is that normal, or something to be concerned about?
