I did all 4 wheels of my lift in 1 day too. What really helps is if you have an impact wrench. My bolts were rusty but a few squirts of PB Blaster and 5 minutes later they came off with the impact wrench fine.

If you don't have an impact wrench then yeah you could have a hard time but the torch will probably do the trick as well. That, and a big cheater bar, and make sure you're using good 6 point sockets that fit right.
