## NHTSA's summary

14313 \- CUSTOMER SATISFACTION. CERTAIN VANS MAY HAVE A CONDITION IN WHICH THE FRONT TORSION BAR MAY FRACTURE DURING OR AFTER BEING LOADED. IF THE TORSION BAR FRACTURES, THE TRIM HEIGHT WILL IMMEDIATELY DROP ON THE FRACTURED SIDE. THE FRONT SUSPENSION ALIGNMENT WILL CHANGE AND THE WEIGHT DISTRIBUTION WILL SHIFT TO THE VEHICLE SIDE WITH THE NON\-FRACTURED TORSION BAR. IF THE DRIVER IS NOT HOLDING THE STEERING WHEEL, IT WILL ROTATE APPROXIMATELY 14 DEGREES TO THE FRACTURED SIDE. WITH HANDS ON THE WHEEL, THE STEERING FORCE FEEDBACK WOULD BE SIMILAR TO A LARGE WIND GUST OR POTHOLE HIT. DEALERS ARE TO REPLACE THE LEFT AND RIGHT FRONT SUSPENSION TORSION BARS.
