What happens when your input shaft is worn out?
When your input shaft bearing is worn out, the gear may slip into another gear when you step on the clutch. A bad bearing causes the input shaft to move too much. As a result, the gear shafts are not aligned properly and cannot be engaged entirely. When you go to shift gears, you may feel vibrations coming from the shifter.
