I lost a rear axle bearing in Boulder,CO on a 69 Bonneville while towing another car cross country in 1977. Not very pleasant looking in the side view as your wheel starts going off the edge of a steep drop. I was able to put a new one on, using the old one as a press against the new one with a piece of pipe over it and pounding with a hammer. It held until I got rid of the Bonnie two years later. That was on a Sunday, no shops open except a parts house in Boulder that happened to have a bearing.
