What's wrong?
The rear suspension on the 2022 Fccc MT45 uses a 13K rear spring assembly to carry weight and keep the chassis supported over the axle. A leaf spring is a stacked steel spring pack, and the spring eye is the rounded loop at the end where the spring attaches to the suspension mount. That loop has to hold the spring in place while the suspension moves under load.
On the affected chassis, the spring eye was built undersized. That leaves less material in a high-stress attachment point, and the assembly process can add stress to the same area. Over normal service, that stress can start small cracks in the spring eye. If the cracks grow, the spring eye can break and the rear spring can detach from the vehicle.
There is no warning sign before failure. An owner or bodybuilder should not expect a dashboard light, noise, or visible symptom before the spring eye breaks.
