I’m planing to jack my car up both front and rear for next oil change so the oil can be drained completely. I’ll use a floor jack to jack up front and back the put jack stands up at the four locations on both sides. I looked at the bottom and saw several locations for floor jack. The front one looks obvious, a square plastic part sticking out near the front axle. However, in the rear side there are two places look like jack point, one is the square flat area of the spare tire cover, the other is like the rear differential. I thought usually the differential is the place to use but I doubt if my floor jack can reach that far. Can anyone tell me which one is the correct jack point?
