What's wrong?
The tie rod assembly on the 2025 Ic Bus Cesb school bus is part of the steering linkage. Its ball studs connect the left and right steering knuckles, so movement from the steering gear reaches the front wheels. The parts must stay hard enough to hold together under steering loads.
On affected buses, the ball studs in certain Dana front axle assemblies were made with less hardness than required. Dana reported that experimental ball studs from an unapproved heat treatment process entered production assemblies. A ball stud built this way can break under use, which can lead to tie rod failure and loss of the normal steering connection between the front wheels.
There is no warning sign before failure. Ic Bus says none is known, so owners and fleet operators need VIN confirmation and dealer inspection to find whether a bus has the suspect front axle parts.
