I do expect to see a differential pumpkin under rear backside of a Toyota Regius 2001 2.7 liter since I believe all rear-wheel drives have one. But in my case I don't see any differential pumpkin under rear backside of a Toyota Regius 2001 2.7 liter)
Are some rear-wheel drives without differential pumpkin under rear backside and a propeller shaft?
According to a quick online search, The this model of Toyota is actually all wheel drive. This indicates that there should be a differential housing in the back. I would recommend taking a closer look under the rear side of your vehicle to verify whether or not the rear wheels recieve engine power.
