It's early Saturday morning so, please forgive me if I'm thinking incorrectly. I believe the mount is attached to the top of the diff with the 4 bolts mentioned so, remove the diff with the mount still attached (remove the bolts from the bushings).

im actually using jimlabs instructions. i have the diff sitting on the bumpstops, but there isnt enough room on the top to get the bolts off. i read elsewhere that the key is to get it as low as possible. one guy did it buy getting the wheels higher in the air to it would look like a "V". so im going to try that next. hopefully that wd40 shower i gave the bolts yesterday do some good.

im only trying to remove the diff mount, so i can get some new bushings pressed in. those 4 bolts do not want to come off though. im worn the hell out trying to muscle them out, but they wont budge. diff is sitting on its bumpstops and i have a good amount of room above it. but i cant get any leverage to losen the bolts. at least i can get my fuel filter changed out.

OH, you are talking about the 4 bolts that mount the case to the bracket.
Yeah man just drop the diff. It takes me about 20 min after the car is on the lift to pull the diff unit out.
A trick when popping the axles out, give them short hard blows. They need to be popped out

Just disconnect all the lower mounting points...outer toe-link, trailing arm, lower 'I' arm and ABS sensor and e-brake cable. The hub should be able to swivel up as you pop the axle spline from the differential.

Just swapped my diff mount out this weekend - the hardest part of the job was just getting everything off to get to the top of the diff.
Remove -
- 2 rear aluminum tranny tunnel braces
- 2 rear belly pans (one aluminum, one plastic)
- Cat-back and main cat
- Power plant frame
- Driveshaft
With that done, unbolt the parking brake cables from the top of the diff - there's 1 12mm bolt holding the bracket on. Then, undo the 2 17mm bolts/nuts holding the "ears" of the diff to the rear subframe. I was able to get to them with the impact gun and an impact universal and extension.
That done, lower the diff. The nose of my diff dipped WAY down, and I was able to pretty easily get a wrench on the 4 nuts on the top. I used a regular 3/8" drive ratchet with a 17mm socket, then had a foot and a half long or so breaker bar on the ratchet. Broke each one loose, then backed them out - mine were not Loctited or anything.
I would also remove the 2 10mm bolts that hold the charcoal canister (the big round black plastic thing) and let it hang down - gives much more room.
Does take a little he-man-ing to get the diff back up and aligned, and would be MUCH faster with a buddy helping. It's also a job that's a lot more taxing on the driveway with jackstands as opposed to a lift, but it's not too bad. Took me most of the day yesterday, but I was also changing my oil.

Cut yourself an access panel in the hatch area. I could not get the bolts loose and had to get my car off of my friends lift, so we had to bust out the drill and tin snips. Made an aluminum plate to cover the hole. I'm not proud of having to resort to that, but I have had to drop diff 3 times since and it saves quite a bit of time, not too mention bloody knuckles!

I'm tried to do it the hard way (ie, leave the Diff in the car).
It's about 100x easier to pull the entire diff out, change the bushings, re-tighten the bolts and re-install.
