i like to put it in 1st gear, get under and undo two bolts. then get up, pop into neutral, rotate DS so you can access the others. put back in 1st. then loosen them.
fox DS bolts (12mm, 12 point) come from the factory with threadlock (be sure to apply some when you get done), so they can be hard to break loose. some guys use a breaker on the bolts (space can be a problem). then they use their leg to push the wrench. if using a box wrench, HC's idea is great. i happen to have some oval metal stock around that fits over wrenches up to about 15mm, so it works as a cheater.
for fun, mark your DS so you can reinstall it in the same orientation you removed it.
good luck.
