cross posts then, I thought you were the sucking post above, hence my comments  Mike

2014 Facelift Discovery

Maybe I was wrong to say the car sucked the wheel up, but the result was, as in the clip above, the wheel changing position within the arch, so something to be aware of maybe. Incidentally, my engine was defiantly not running and my tailgate was definitely open when this happened to me

Wish I read this two days ago, I had serious concerns about jacking it, the compressor made all sorts of sounds when I jacked it from normal height. I'll do off road next time, it all seems to be working okay, but that sort of info needs printed BIG on the jack or in the kit they supply if its a chance to damage your vehicle.
