2002 MAZDA 626 Tires Problems

HEARD NOISE AND BAD VIBRATION FROM FRONT LEFT , IT GOT WORSE AND LOUDER WHEN MAKING TURNS. TOOK VEHICLE TO DEALER, WHO STATED THAT FRONT WHEEL BEARING WAS BAD. AROUND TWO WEEKS BEFORE THE SAME THING HAPPENED, HEARD LOUD NOISE ON FRONT RIGHT, GOT LOUDER WHEN TURNING. TOOK VEHICLE TO DEALER, WHO REPLACED FRONT RIGHT BEARING. CAR ALWAYS SERVICED AT DEALER, TWO WEEKS BEFORE TOOK CAR TO DEALER FOR PULLING TO THE RIGHT. DEALER STATED IT NEEDED AN ALIGNMENT AND BALANCING. DID THAT NEXT DAY AND SAME THING HAPPENED WITHIN THE PAST MONTH. I HAD NEW FRONT BRAKES, NEW TIRES, NEW RIGHT AND LEFT BEARINGS, AND SEVERAL ATTEMPTS TO BALANCE AND ROTATE TIRES. ALSO HAVING PROBLEMS WITH TRANSMISSION, BUT DEALER INSISTED THAT NOTHING WAS WRONG, SOMETIMES THE CAR WILL NOT CHANGE GEARS LIKE IT SHOULD WHEN GOING OVER SPEED BUMPS. VEHICLE STALLED SEVERAL TIMES. ALSO, HAD TO REPLACE COOLANT BOTTLE...
