| Description of the problem | Noticed abnormal tire wear on front tires. Took vehicle to shop to have tires rotated and alignment checked. A safety check revealed both front coil springs were broken.(see photos) fracture occurred at the transition from tight radius (pigtail) at the bottom, to larger radius. The spring then bowed out of column and started rubbing the strut body. Vehicle previously had a safety check at the same shop at 47726 miles on 1-20-2016 with no spring defect noted. Defect was noted at 60800 miles on 4-13-17. Report generated by original owner. Left spring failure was not noticed but right failure may have occurred when encountering normal pothole that created a startling bang not commensurate with the depth of the street defect. Owner did not notice any steering wheel displacement associated with a wheel misalignment. Owners concerns. 1) vehicle was less that 7 years in service less that 61000 miles. 2) essentially a silent failure, first clue was abnormal tire wear. 3) mode of failure could allow spring to pass over perch causing sudden complete collapse of that corner suspension. 4) if spring remains in place, rubbing on strut body will cause failure of the strut itself affecting handling. Pictures are of rt. Strut assembly. Lt strut was discarded before decision to report was made but had similar failure, |
