Got halfway through the first corner of the car (front passenger) and ran out of time

So I undid the spring compressors and left the stock spring on. I didn't replace the bush, but I replaced the drop link.
I lowered the jack down and pulled it out from the car. All of a sudden... "creeeeeeeeeak...BANG!"
Anyone care to take a guess what it is?
