Question

Quizplus · Accepted Answer

The output or mainshaft bearings are part of the transmission that would be under load when the vehicle is in gear (forward or reverse), which could cause a rough growling noise. The pilot bearing is involved when the clutch is engaged or disengaged, not specifically related to the noise when the vehicle is moving in gear.
