I decent socket set and box end wrenches. If you have some rust I'd start spraying the hardware down day or two in advance so it penetrates deep. I did mine on the ground. Took about an hour but I have air tools.
Could you confirm the torque specs: 70 lb-ft for upper bolt and 85 lb-ft for lower bolt? :nerd:If you're just doing the shocks it's not a terrible job. You'll want penetrating oil, a decent sized hammer, a half inch drive metric socket set, and a metric wrench set. If possible, a torque wrench and some anti-seize are recommended.
Spray penetrating oil on the upper and lower bolts a couple times a day for a couple days before tackling it. Try to really get the oil in there.
I found the best way to do it was to lift the whole back end up, take off both tires, then lower the jeep onto jack stands, allowing the axle to sag. Place your jack under the centre of the diff.
Undo the lower bolts, then use the jack to lift the rear axle to take weight of the shocks. The bottom bolt should be able to be easily tapped out with a hammer. Then just remove the upper bolts and the shocks.
Install the new shocks upper bolt first, then use your jack to raise or lower the axle to get the lower shock bolt lined up and install the bolt and nut, torque to spec.
If you have anti-seize, but a light coating on the threads of the bolts before you put them back in
