The bumpstops being worn and basically nonexistent was the issue with mine when it was loaded with at least 300lb of people and cargo. Your QX4 being a 99 model is probably the same issue. I ordered from Amazon the Air Lift airbags for the rear shocks and it resolved that. It had actually slipped my mind that I had them installed since I was driving my other vehicle. So for about a month I wasn't checking the pressure on the bags, now they won't hold any air.
