Looks like that jack was side loaded to the maximum, it is evident from the way it failed.

Never had any problems with my jack. I have another just like it out of my old Eagle that I used to jack up my truck, too, never any problems with it either.

I've used an impact wrench to jack up my car in the past with the OEM jack. Properly placed, and properly used, they are good jacks.

The fact that this failed to the SIDE tells me it was improperly used. All the load should be vertical.

I've used the factory jack for years with no issues. Like Will said, vertical lift only. There'* places on your car marked where the jack should go.

Never use any jack, I don't care if it'* hydraulic, to hold up the car. Use jack stands, or large wood/cinder blocks. Even hydraulic jacks are known to drop a car. It'* just really not made to hold it up for duration.

Well, regardless of how it was used, in what direction, etc.... I am glad to hear you are ok.

Two guys around here last year got hurt on the same day. One guy was crushed by his tractor when the hydrolic jack blew and died. The other guy was pinned under his car all day. Bruised&broken ribs and dehydration. Odd they both happened on the same day a hundred miles apart.
