Down to the radius arm bushing now: nuts are very hard to get off and then the bolt is seized in the bushing: since there's not much space to get a good whack at it, does anyone have a good trick other than trying to cut the bolt by getting a cutting disk between bracket and bushing?

Thanks for any hint

 

If you can't drive it out, then it's sawzall time. A cutting wheel will be more likely to cut things you don't want cut.

 

Good. that's something I got. always used it for wood demolition. I'll get some metal cutting blades and give it a try.

Cheers!
