I have done a couple of sets now on GQ and GU utes, didn't find them hard to do at all, nuts were as tight as you would expect, just use a long braker bar and a shorter one and smack the shorter on with a hammer, the ones I have done have been +16mm
I also so found use the longer braker bar and get it in the right position and lay under the car long ways and give it a good kick with the bottom of your foot works a treat too, and I don't jack it up at all, that way you can use the wheel to roll the diff forward or backwards as needed, just chock front wheels and have hand brake of and out of gear, also easier to do one side at a time I found
