The problem
THE AXLE HOUSINGS WERE MANUFACTURED WITH A TIGHT FRICTION WELD CURL RADIUS ON THE INSIDE DIAMETER OF THE AXLE HOUSING. UNDER OPERATIONAL LOADS, CRACKS CAN INITIATE AT THE WELD CURL RADIUS ON THE INSIDE OF THE HOUSING. THESE CRACKS MAY PROPAGATE, EVENTUALLY ALLOWING THE AXLE SPINDLE TO SEPARATE FROM THE AXLE HOUSING.
Risk
SEPARATION OF THE AXLE SPINDLE FROM THE AXLE HOUSING CAN RESULT IN LOSS OF VEHICLE CONTROL AND A POSSIBLE ACCIDENT.
What owners should do
DEALERS WILL REPLACE THE REAR AXLE HOUSING WITH A NEW HOUSING.
