There are mechanical LSD's,although clutch types are more popular due to theyre ability to be rebuilt. That diagram didnt specify whether or not the differential was open. If the traction control was causing the 2 stripes, they would alternate, and never mirror each other. In other words.. 2 dark black stripes that look the same next to each other means the axles are locked. period. Can I ask where the open diff info came from? I read on chryslers site under features where it says limited slip-N/A too, but it might be some kind of mistake. Has anyone here actually left one stripe in a straight line?
