It's the front bushings mounted up against the frame. (in the middle of the swaybar) I was looking around town today, and on the internet and Energy Suspension doesn't have any for an H2. ??? I figured they were the same as any other part for a Chev/GM truck.
My swaybar links, behind the tie rods, were replaced a month ago. Those bushings no longer existed.

This trouble is brand new, like I drove it on Sunday, and noticed it backing out of the driveway the next morning. I did pull a heavier load than normal over a cra p p y road though.
My dealership said they could have stock ones sent in for 19.00/each.
I kinda wanted the ones you can grease. The dealership had another name for the part. I think it was anit sway sleeve, or something. sorry can't remember.
I had hoped that I could get the grease-able synthetic kind from Energy Suspension and be done with it ...
