NHTSA Complaint #10169511 — 2002 TOYOTA SEQUOIA

IN 8/06 I NOTICED A ROARING/GRINDING NOISE COMING FROM MY END. L. BEARING REPLACED X2. PROBLEM REMAINED. THEN REPLACED THE RIGHT FRONT BEARING. STILL TO NO AVAIL. I THEN TOOK MY CAR TO TOYOTA IN TAMPA WHO STATED THE REPLACED BEARING HAD BEEN PRESSED IN TOO TIGHT. I TOOK MY CAR BACK TO THE MECHANIC WHO THEN TOOK THE ENTIRE ASSEMBLY OVER TOYOTA IN CLEARWATER TO REPLACE THE ENTIRE ASSEMBLY. STILL NO RESOLUTION. TIRE PROBLEM? SO, I TOOK IT BACK TO THE TIRE KINGDOM WHO PUT ON NEW MICHELIN CROSS TERRAIN SUV TIRES. PROBLEM REMAINED. SO I TOOK IT BACK TO THEM AND THEY THEN PUT ON A NEW SET OF MICHELIN LTX TIRES. PROBLEM REMAINED. SO, I THEN TOOK IT TO COLLISIONTEC IN CLEARWATER, THINKING THAT PERHAPS TIRE KINGDOM MIGHT HAVE BENT SOMETHING WHEN THEY ORIGINALLY ROTATED THE TIRES. (THE CERTIFIED TOYOTA MECHANIC HAD PREVIOUSLY INSPECTED EVERYTHING UNDER MY CAR WHEN HE FIRST HAD IT BUT HAD BEEN UNABLE TO DETECT ANY DAMAGE). COLLISIONTEC DROVE THE CAR AND DID AN INITIAL INSPECTION, BUT COULD NOT DETECT ANYTHING. THEY HAVE ASKED TO HAVE ME BRING THE CAR BACK SO THAT THEY CAN KEEP IT FOR A WEEK AND DO A COMPLETE INSPECTION. IN THE MEANTIME, MY CHECK ENGINE LIGHT CAME ON AND THE VSC/VTC LIGHT CAME ON, SO I TOOK IT BACK TO THE TOYOTA MECHANIC. THE O2 SENSOR NEEDS TO BE FIXED/REPLACED. TO FIX THE VSC/VTC TOYOTA DOESN'T SELL THE ONE PART NEEDED, ONLY THE COMPLETE SET FOR $900! THIS IS ALL ON TOP OF THE ORIGINAL ROAR/GRINDING/VIBRATION PROBLEM WHICH STILL EXISTS!! REAPAIRS NOW UP TO 2K & NO RESOLUTION. ALSO, MY CAR WAS RECALLED FOR THE BALL JOINT PROBLEM. THERE IS NO STICKER INDICATING BALL JOINTS REPLACED. IF THE BALL JOINTS WERE NOT REPLACED AS THEY SHOULD HAVE BEEN, COULD THIS BE THE SOURCE OF THE ROAR/GRINDING/VIBRATION? THIS ROAR/GRINDING/VIBRATION IS COMING FROM THE FRONT AND OCCURS ONLY WHEN THE CAR IS IN MOTION. *NM
