axle and rear upper control arm bushings
What is the easiest way to remove the rear upper control arm bushings at home. The rear upper control arm bushings are on the frame and on the axle what is the easiest way to remove the bushings that are on the axle?
To remove the bushings that are in the axle, drill a bunch of 1/2" holes in the rubber. The heat and missing volume will make the rubber part slide out easily. If the casings are in good shape, just use the rubber from the new bushings and slide them in. You can freeze the overnight to shrink them a bit. If you are intent on replacing the entire shell, remove the rubber part as described above and then take a hacksaw blade and cut a slit from the inside at approximately the 9 o'clock position. You can then hit the outer shell of the bushing from the outside with an air hammer or a hammer and chisel. They should collapse into themselves. You can pretty much remove any control arm bushing that way.

That article is informative but aren't all the '68-'72 A-body upper rear bushings pressed into the axle housing?
"Each control arm has two pressed-in bushings, one at each end."
Here's a thread with some info.

This post is about 80% wrong.

That is pretty slick!
Probably best to keep one "strong" bit around for this purpose only, maybe use an old dull bit though. The cheapo ones would probably snap pretty quickly.
Cool, quick solution though. Might not be as easy to access under the car though.

OK, yes the right angle drill would be a big plus to doing it under the car. It would be worth the $20 to go rent one from the local rent-all shop to not have to remove the rear, that's for sure.

The bushings on the axle of GM A body cars are a one piece part (steel sleeve and vulcanized rubber center with a sleeve). They are not rebuildable.
You can use a number of methods to remove them, but the best way (and factory SM way) is to use a tool to press them out and press them in.
I use a ball joint press to do the work. Easy to do, and prevents any damage to the ears on the axle housing.
If to look at a FSM, they show how a press is used.
