New compressor and bags...easier with suspension hanging free?

I'm going to put a new compressor and bags on the rear of my 2007 denali, and want to know if it easier with the frame jacked up, and suspension hanging, or with the wheels up on ramps. Makes sense the suspension should be hanging, but wanted to ask those who have been there.

Thanks for the answers. Jim

I did the rear shocks with the axle hanging and then a jack under the diff to make sure it didn't over extend without the shocks. I think it will be eaiser like that, if not you'll have to compress the shock to fit. not really hard to do but eh.

I just did the rear shocks and compressor on my 08 on different days. For the shocks I let the suspension hang and then put a jack under each side of the axle as I did each shock so there was no tension on them and the bolts could slide out easy. Pull the inner fender liners for better access to the top bolt. You can use a ratchet on the inside of the top bolt with a short extension ( I used 1/2” drive) and a wrench on the outside and “ratchet” the wrench back and forth instead of ratcheting the ratchet because there’s no room for that,. You can’t get a standard wrench on the inside of that bolt. I also broke them loose with an impact. The compressor… doesn’t matter but if you’re doing both at the same time, while it’s up there…

for me, the only reason to raise the rear end up is so my fat àss can fit under there. No need to hang the rear axle loose for shocks or compressor.

I’ve actually changed the compressor with all four wheels on the driveway.
