    HEAT FROM THE NEW DEF REQUIREMENTS ARE CAUSING PROBLEMS. THE HEAT OFF OF THE DEF SYSTEM STAYS TRAPPED UNDER THE VEHICLE. WHICH IS CAUSING EARLY WEAR ON ELECTRICAL HARNESSES ALONG WITH AXLE SEALS. I'VE REPLACED 3 WHEEL SEALS AND 2 FRONT DIFFERENTIAL SEALS. THE DEF HARNESS HAS FAILED TWICE NOW. PLEASE LOOK INTO THIS. THE HEAT STAYS UNDER THESE VEHICLES. AND THE MANUFACTURER WILL NOT ACCEPT RESPONSIBILITY FOR THIS. *DT*JB
