try putting an oil based lubricant on it. like liquid wrench or something. its prolly rusted in there pretty good. also instead of using a 3/8 rachet try using a 1/2 breaker bar for the 21mm bolt.

hope that helps

have fun. sounds like the bolt is rusted into the metal sleeve in the bushing. the only thing that i can think of to work is a hacksaw. get it between the k-member and the arm and cut the bolt. other than that, a torch.

Get some PB Blaster...and if you have access to air tools, use an air hammer on it.

I got out my big flat blade screwdriver (you know the one that doubles as a prybar.) and my 2lb hammer placed the flat blade of the screwdriver on the end of that bolt and beat the living **** out of it till it gave up. PB blaster helps the process along but most of it is just brute force.

I had the same problem with mine that had been on there for 120K miles.

I went and got one of those really pointy air hammer attachments and ground it down so it was not so sharp. Then I put the nut on the end of the bolt just enough so that the air hammer would not slip off the end of the bolt. Then I just went to town on it with the air hammer which eventualy got them out.

Prior to that I had tried sevral things that involved a big sledge hammer.
