Now I don't KNOW if mine are seized but I'm mentally preparing to install the UCAs tonight and this is the only possible snag I could think of, has anybody encountered this and how did you tackle it? It doesn't look like there's enough space in there to swing a hammer...
For whatever it's worth, I don't think you'll have a problem. My truck is rusty as hell. A lot of things have been seized when I went to remove them but not the UCA bolts. They came right out.
