I think, that's the upper bushing (based on the parts fiche and number). But that might be the one and the same. Thanks sir.

On my next tear down...I want to install urethane spring bushings. I run a spring over and no trackbar...so the axle has quite a bit of side-to-side movement with the stock rubber bushings. I think they are no different from the typical Jeep/Chevy leaf spring bushings that have been around forever.
If you see fuel tank stripes on your rear driveshaft, then it could be due to the flemsy rubber bushings.

Quick question. We are on day 3 of trying to get bottom bolts out and still no dice with all above said pointers. If we end up having to cut bolts and come to find out we ruined the rubber bushing in the leaf on the btm bolt will the upper sleeve bushing ( Genuine GM 14027938 Spring Shackle Bushing, Rear https://www.amazon.com/dp/B00GUAEGEK..._H3fExbVP5RYV0 ) slide in or will I need to replace the whole leaf?

It sounds like the bushings are shot with all the spinning and pounding. You dont want to do this job again I would use all new bushings and bolts. any spring shop should have what you need, and dont forget the anti seize.

The car has almost 151k miles on it I am sure they were already shot before I even got to them. I'm sure the great NEPA seasons and massive amounts of salt on the road helped that.

I found this layout of the back of the h3. So my question is for anyone else who had a hell of a time getting them out and had to replace bolts/nuts/rubber bushings did you need to replace
the whole leaf spring after the bushing at the end was destroyed, or does the top rubber bushing also fit into the end of the leaf where bolt came out? I am not sure what to expect when we
get them off so I would rather have new springs or bushings waiting to go in... Any help would be greattttt. Thanks!

Nothing special about H3 leaf spring bushings. Find some 2.5" urethane bushings from a Jeep or GM truck and press em in. Energy Suspension or Daystar is prolly your best bet. Also...you might use a 2008 Colorado for the application (same bushings). I've noticed that Hummer is starting to disappear from parts listings.
A sawzall works good for cutting the bolts...an oxy/acet torch works good to burn the old bushings out.
