Final answer:
In a non-locking differential, if one axle is turning at 96% of case speed, the other axle will also be turning at the same speed.
Step-by-step explanation:
In a normal or non-locking differential, if one axle is turning at 96% of case speed, the other axle will also be turning at the same speed, which is 96% of case speed. This is because in a non-locking differential, the power is distributed equally between the two axles, allowing them to rotate at the same speed.
