Power train

17 reports
“WHILE DRIVING, I STOPPED AT AN INTERSECTION. WHEN I STARTED TO GO, THERE WAS A LOUD GRINDING NOISE AND THE CAR WOULD NOT MOVE. I HAD TO GET THE CAR PUSHED OUT OF THE INTERSECTION. I TRIED RESTARTING THE CAR AND AS SOON AS YOU PUT IT IN GEAR, YOU HEARD THE GRINDING NOISE. I HAD IT TOWED TO MY LOCAL MECHANIC, UPON HIS INSPECTION, THE FRONT DRIVE SHAFT WAS BROKEN AND THEN DISCOVERED THAT THE INSIDE OF THE TRANSFER CASE WAS ALSO STRIPPED. SO NOW I'M STUCK WITH NO VEHICLE, THOUSANDS OF DOLLARS IN REPAIRS, AND THIS IS THE SECOND TIME THIS HAS HAPPENED TO ME, THE FIRST WAS IN JANUARY 2017.”
