2016 Toyota 4Runner Suspension

This vehicle has experienced the front coil spring cracking on the right front, the left front cracked at 114K miles. This is a very common issue with 2015-2017 Toyota 4Runner TRD-Pro, it is a design defect in the way the coil spring terminates and sits on the top hat and bottom spring perch. Toyota has discontinued the defective parts and redesigned the spring perch on the updated strut and uses a different spring, but it is not recalled and should be as this is a safety defect. A broken coil spring can cause sudden loss of control of the vehicle resulting in a crash and even death.

THE 2016 4RUNNER TRD PRO IS A LIMITED PRODUCTION MODEL. TOYOTA SOURCE THE SUSPENSION COMPONENTS FROM AN OUTSIDE VENDOR. MY RIGHT FRONT SPRING FAILED, BREAKING I FOUR PLACES. THE CAR HAS 41,000 MILES AND HAS ONLY BEEN USED IN NORMAL HIGHWAY DRIVING -- NO OFF-ROAD. THE FRONT SPRING DESIGN IS DEFICIENT. THERE IS NO TAPER AT EITHER END OF THE COIL SPRING, LEAVING A KNIFE EDGE TOUCH THE ADJACENT COIL -- RIGHT WHERE THE SPRING BROKE. THERE ARE NUMEROUS EXAMPLES OF THE SAME PROBLEM ON THE INTERNET. THE PART WAS BACK ORDERED REQUIRING MORE THAN A WEEK TO GET IT, SUGGESTING MANY OTHERS HAVE HAD THE SAME PROBLEM. THE LEFT SPRING WILL LIKELY FAIL, AND THE RIGHT WILL PROBABLY FAIL AGAIN. THIS IS A SAFETY ISSUE AFFECTING STABILITY.

WHENEVER I GO OVER POTHOLES AND BUMPS MY CAR MAKES CLUNKING NOISES AND SOUNDS HORRIBLE.

TRD PRO MODEL FRONT SHOCKS MAKE A CLUNK BELOW 40 DEGREES. TOYOTA T-SB-0054-16 TOYOTA WON'T LOOK AT.
