How do you determine if 1996 Infiniti g20 has posi-traction?

To determine if a 1996 Infiniti G20 has posi-traction (limited-slip differential), check the vehicle's owner manual or specifications for the differential type. You can also perform a simple test by spinning one rear wheel while the car is off the ground; if the opposite wheel spins in the same direction, it likely has posi-traction. Additionally, inspecting the differential for any identifying tags or markings can help confirm its type. If unsure, consulting a mechanic or Infiniti dealer can provide a definitive answer.
