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

[11bravo]

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

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.

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.

Beware, these GM with AWD have an open diff. If the rear is jacked up, THE TRUCK WILL ROLL if on an incline whether in P or not.

Block those front wheels! The 08-13 hybrid Denali & Esky are 4WD so no roll with their closed diffs.
