What's wrong?
The right rear half shaft on a 2022 Ford Mustang Mach E is the axle shaft that sends power from the rear drive unit to the right rear wheel. When the vehicle accelerates, the half shaft twists under load and lets the wheel turn while the suspension moves up and down. The part needs enough wall thickness to hold that force.
On affected vehicles, the right rear half shaft was made with the outer race wall thinner than Ford specified. The supplier's lathe removed more material than intended because the part was not seated correctly during production. Ford says the wall thickness inspection was suspended because of manpower shortages, so uninspected parts were assembled into finished right rear half shafts.
There is no warning sign before failure. Ford says the driver would not perceive a warning before the right rear half shaft stem breaks under load.
