I replaced the exhaust bushings a couple of days ago & thought I would share how I did it.

I first cut the rubber close to the edge. I then used a file to weaken the outer metal edge being careful not to file the frame. I was then able to pop it out with a punch & hammer.

To get the new ones in I used a piece of all thread, small piece of pvc pipe & some fender washers. I used these pieces as a press to get them in.
