Transmission & Drivetrain (A2/A3)Pregunta 22 de 120

b.The transmission to shift gears
c.The drive wheels to rotate at different speeds during turns
d.The engine to idle smoothly
Explicación
The differential splits torque to the drive wheels while allowing them to turn at different speeds when cornering, since the outer wheel travels farther. A limited-slip design adds resistance to reduce wheel spin. Whining or howling noises often indicate worn or improperly set-up gears.
