Hello all, i've got a 2001 explorer sport, i've yet to need to jack up the rear of the vehicle for any thing yet. But the jacking instructions say to position the bottle jack under the axle. I keep thinking to myself, that this can't be good for the axle, yet this is what the instructions appear to say. I can't see anywhere else to do it though. On the front, there are hooks to position the jack under. Is this right correct for the rear though?
