I posted this on another forum a while back. I learned a very valuable lesson from a mechanic friend of mine and wanted to share:
I got an education on this a few months back.
I had always done it this same way, drilling and cutting out the bushings. On the corvette, this time I just didn't want to get into it and I figured I'd pay someone to do it while I worked on something else. So I took the A arms across the street to my mechanic buddy and said I'll leave 'em with you and pick them up tomorrow. He said "just wait a minute and you can take them back with you" I'm like whaaa?
So he chucks one in a vice and picked up an impact hammer with a wide blade on it, puts the blade between the flanges of the bushing and the A arm, hits the trigger and guides the bushing right out!
No stress on the a arm, no work, all four arms done in 5 minutes! Just buzzed them right out, shells and all, all the bushings laying on the floor! I said I've never seen that done before, he says what?, I always do 'em like that. He's a good friend and wasn't even going to charge me, so I gave him a twenty and said this ain't for removing the bushings, it's for a damn good education!
I love learning things like that.
