Show answer

Correct answer to question 141 (Auto & Shop Information): transfers some torque to the wheel with more traction when one wheel starts to spin

Method

An open differential sends power to whichever wheel spins easiest, which can leave a stuck vehicle stranded; a limited-slip design resists that and shares torque with the wheel that still has grip.
