releasing for turning a corner, understandable, but I'm talking about acting as an open axle when you drop one wheel in a hole in a grassy yard in a straight line. Tire setting on solid ground sits still while other one spins, unless, you tap on the brake pedal at which both wheels will spin until you release pedal. Service tech at dealer was schooled on this trac-rite and says it's sounding as if the carrier is set-up too loose. Have an appointment first of the week, says if they can't find something visibly wrong they will contact AAM about new replacement.
