What's wrong?
The U-bolts on 2023-2024 Micro Bird G5 School Bus models are heavy curved fasteners that clamp the front leaf spring assembly to the axle. The leaf springs, called suspension blades in the filing, help carry the bus weight and keep the axle located as the bus moves over bumps. Those clamps have to stay tight so the spring and axle work together.
On affected buses, longer IMT Standens U-bolts were installed when supplemental suspension blades were added to certain GM-based vehicles. Some of those U-bolts broke during vehicle preparation and in service claims. Micro Bird has not identified the exact cause, but a broken U-bolt stops holding the suspension blade the way it is supposed to. That loss of clamping force can let suspension parts shift and increases the risk of a crash and injury.
There is no warning sign before failure. A driver should not count on noise, handling feel, or a dashboard light to appear first.
