You want to turn the wheels to the left so the pit man arm is out of the way that will help. I definitely second removing the relay rod and the shock absorber to give yourself more room. I found that you can leave the lower mounting bolt in and put a jack underneath it and then pull the top bolt. Lower the jack and the differential will rotate around the lower bolt and drop down real nice. Reinstallation also work good this way you just have to get the top mount above the frame then use a jack to rotate the differential about the lower bolt. In order to get the proper alignment of the top mount I also used a small car jack on the left and right side of the differential in addition to the main jack under the differential housing. This worked out super slick.
