Advanced Vehicle Template: Back wheels problem

To the point:

I’m trying to edit the advanced vehicle mesh found in this template ( to my own model but when I check to see if all the behaviors of rotation are similar to the original (using blender), I get this weird effect when trying to rotate the back wheels around the bones they are associated to (VisWheel_BL and VisWheel_BR).
