The bushing where the shock meets the swing arm on my '07 450 EXC has gone bad... squeaky, loose...a bit of wear where the bottom of the shock mounting "ears" are actually rubbing on the "eye" on the swing arm. I removed the shock. How do I remove and replace the bushing? It appears to be rubber and plastic. I could just place a slightly smaller diameter socket against it and try to drive it out, but thought there might be a proper way that I don't know about.
