Compressing a strut to get wheel back on...

[NittanyX5]

This may seem silly or funny but I was removing the skid plate from the bottom of the X5. To get to a couple of the six hex bolts, I found it easier to remove the front wheels. I put one wheel back on, went into the house and when I came back to the garage, the rotor for the other wheel was so low that I cannot get the wheel lined up to the correct height to reinstall the wheel. I don't know if the suspension tried to level itself and overcompensated for the missing wheel or what. The bottom of the rotor is about 4 inces from the floor.

My question is: how do I get the strut to contract or go back up? I have a 2-ton jack in the front of the truck raising the X5 by the block that is right in front of the skid plate that I removed. I also have two 2-ton jack stands that aren't occupied yet.
