I have a question for anyone who has replaced the rear axle bushings, or who has experience with these kinds of things:
What do you use to press the new bushings into place? I mean specifically the kind of arbor to use to push on them, not whether to use a hydraulic shop press vs. a forcing screw. The problem will be is the same it seems to me whichever tool you use to do the shoving with.
Here is a video of the operation, done in this case with a forcing screw:
(Skip ahead to 2:15 to get to the reinstallation part and the tools used)
The arbor used to push the bushing in here looks like your basic stepped arbor - one side stepped, the other side flat. If the arbor is what it seems to be, you will be pushing on the center steel sleeve of the new bushing. It will get compressed and displaced like
a quarter or 1/8 inch or so before you start making contact with or can press on the surrounding rubber material and/or outer casing. Seems like a bad idea! It appears to work for this guy, but it can't be the right way? There is a very thin ring of steel exposed around the rubber puck, and I actually do have a wheel bearing cup that (just) catches that edge. But that seems like maybe not enough to push on safely? The steel casing isn't very thick and the exposed ring is minimal area. It might possibly deform or crack under pressure.
I also have another arbor/cup out of the same wheel bearing kit that can make contact with the rubber cup avoiding the center sleeve. But it's not going to be spreading its force out over a wide area of the puck. Possibly I could find massive washers to help spread out the force. Don't want to be cutting into the rubber or polyurethane material with a thin edge.
What did you use? Or if you can't recommend that, what do you wish you had used instead?
Ideally I'd have a steel arbor turned on a lathe to be exactly the inverse of the shape of the new bushing (on its inboard face, minus the center sleeve), but if I went to that kind of expense, I might as well junk it all and buy a new car. It seems the next best thing might be a used bushing, with the center sleeve cut out, flipped around so that the rubber puck surfaces match up. But these parts seem to get gnarred up very badly during extracting - if you're chiseling the old one out like this guy did.
Thanks for any advice!
