Where did you put jack on the front of truck? It is supposed to go on the edge of the rail, behind the front tire, specially marked spot. Hard to believe GM's designer missed something as basic as this.
If all I am doing is changing a flat on the road, I would likely cheat and put the jack underneath part of the suspension, so that the suspension did not sag down and require me to jack higher than I wanted. If rotating tires, I would typically use my roll around jack and some jack stands in some combination, would never mess with the truck's jack. Now you have me thinking i better go check out the jack in my spare time.
