Idler arm bolt
Well as you can see, I was the starter of this here thread and my installation went without a hitch.
I did the following:
Jacked car up and rested on jack stands (whole front end), could get away with just passenger's side though.
loosed and removed nut.
Popped out lower bushing.
Pried out top bushing with bolt still passing through it, not a hard thing to do.
With top bushing now sitting on top of where it had been pushed into I was able to angle bolt and push out easily past the exhaust. Top bushing and all.
Assembled in reverse order.
Even if you were not able to pry the top bushing out prior to dissassembly and had to cut the bolt, I would think you could reasemble using this technique.
