2004 Toyota Highlander Wheels Problems

I HAD A FLAT TIRE ON MY 2004 TOYOTA HIGHLANDER. MY HUSBAND AND I WERE GOING THROUGH THE TIRE REPLACEMENT STEPS AND HAD THE VEHICLE JACKED WITH THE MANUFACTURER PROVIDED JACK. AFTER REMOVING THE LUG NUTS, I WENT TO REMOVE THE FLAT TIRE FROM THE WHEEL STUDS. THE JACK POPPED OUT OF PLACE AND BENT, AND IS NOW UNUSABLE. WE HAD TO FIND A HEAVY DUTY JACK TO LIFT THE VEHICLE TO GET THE TIRE OFF AND PUT THE SPARE TIRE ON. SPARE WAS PLACED AND PROPERLY TIGHTENED. NOW, THERE IS A SCRAPING SOUND WHEN DRIVING THE VEHICLE AT ANY SPEED. I HAD FLAT FIXED AND WHEN TIRE COMPANY REMOVED SPARE, ONE WHEEL STUD FOR FRONT PASSENGER SIDE BROKE OFF. TIRE COMPANY SAYS THEY'VE SEEN THIS NUMEROUS TIMES WITH HIGHLANDERS; THE INTEGRITY AND/OR MACHINING OF THE WHEEL STUD APPEARS DEFECTIVE. *JB
