Limited Slip Differential:

A Limited Slip Differential (LSD) is a type of differential that allows for some differentiation in wheel speeds while still providing some traction to both wheels. In a standard open differential, power is sent to the wheel with the least resistance, which can result in loss of traction if one wheel slips. In contrast, a limited slip differential limits the speed difference between the two wheels, ensuring that both wheels receive power even if one loses traction.

Technical Explanation:

Common Symptoms:

  1. One wheel spins excessively while the other does not receive power.
  2. Difficulty turning or handling the vehicle.
  3. Tires wear unevenly.

Diagnosing:

  1. Perform a visual inspection of the differential for any leaks or damage.
  2. Test drive the vehicle to observe any unusual noises or handling issues.
  3. Jack up the vehicle and rotate each wheel to check for resistance.

Common Repairs:

  1. Replacing worn or damaged clutch packs inside the LSD.
  2. Refilling or replacing the differential fluid.
  3. Adjusting the preload or torque settings on the LSD.
