NHTSA Complaint #11289962 — 2003 BMW 325I

DRIVING ON 12/12/2019 ON INTERSTATE HIGHWAY ABOUT 65MPH, GOING STRAIGHT, WHEN ALL OF A SUDDEN REAR WHEELS (THIS IS RWD - 2003 BMW 325I) LOCKED UP COMPLETELY - THE VEHICLE WENT FORWARD AT ABOUT 45 DEGREES SIDEWAYS BEFORE IT STRAIGHTENED OUT WHEN THE SPEED DROPPED. THANKFULLY I DID NOT HIT ANYBODY, AND NO ONE HIT ME ALTHOUGH THERE WAS QUITE A BIT OF TRAFFIC ON THIS MULTI LANE INTERSTATE. I GOT AAA TOW IT HOME. HE HAD TO DRAG IT ONTO THE TRUCK BED AS THE REAR WHEELS CONTINUED TO BE LOCKED UP. WHEN I REMOVED AND OPENED THE DIFFERENTIAL TAPERED ROLLER BEARING ROLLERS WERE IN THE OIL SPACE. LOOKING TO SEE WHERE THEY JAMMED THE SYSTEM UP I NOTICED MARKS ON THE CARRIER. IT APPEARS ROLLERS JAMMED UP IN BETWEEN THE CARRIER AND THE INNER WALL OF THE DIFFERENTIAL BOX - SEE PHOTOGRAPHS. THEY MAY ALSO HAVE JAMMED UP IN BETWEEN THE GEARING BUT I DID NOT NOTICE MARKS ON THE TEETH BUT DID NOT HAVE TIME TO SPEND TO LOOK MORE CLOSELY.
