I know this doesn't really really belong here, but I'm in desperate need of help. I'm trying to replace the brake rotor on my friends mom's 96 Land Cruiser, and I seem to have removed everything holding it on - wheel, studs, lock retainer, greese cap.
Here's a picture of where we are.

What do I do now? The thing is just...on there!
HELP! NEED TO GET THIS DONE!
