Don't give up like I did.
My trailblazer linkage failed at these bushings. I had to be towed and got lucky when the tow truck driver released my truck, it rolled just up on a curb so I was able to go under easily. But it was nasty in a gutter at a shop. I tried and tried any configuration for these pieces. No go. I left it with the shop. Didn't have or have a way to get any soap, lube or anything that would help. Not even spit. Take something to lube it, in case you need it. No tools required. Just lube.
