Gosh, with the stuff at you disposal, you could remove all of them in an hour.

I went the cave man route,
and drilled a bunch of holes through the rubber until I could manually push the inner liners and rubber out,
and then used a hammer and screw drive to drive the outer sleaves out.

You could use sockets to keep the arms from crushing, and press them out.

I've heard of guys burning the rubbers out with a torch, and tapping out the outter shell as I did.

Anyway you do it, just pay attention, that you don't compromise the integrity of the arms, and you'll be fine.

I have very little experience, but with advice,
and a little help from a more experienced brother,
I managed it.

As for the install, I put the new bushings in the deep freeze, a couple days before the install, made sure the holes were clean, and slightly greased, and they went in pretty easy, a couple of wacks with a hammer, and a block of wood.

With a good selection of mandrels and your hydraulic press, the job will be like falling down stairs. The old bushings will come out without removing the rubber. Just use a mandrel that is slightly larger than the flange on the shell, support the back of the bushing on the trunion (crosspiece of the press), fashion a support that fits snuggly between the two sides of the arm, and press. This is to keep from collapsing the sides of arm as you press the shells in and out. For a support, I used an appropriately sized PVC pipe, cut to length and sectioned in half so it fit around part of the bushing shell inbetween the two sides of the arm. Is this making any sense?? When installing them, put the bushings and shells in the freezer for an hour or so, so the bushing will push out of the shell. Press the shell only into the arm using the same mandrel and support and then take the bushing back out of the freezer and push it into the shell. Once you've done one, the rest will come easily.....

Now would be a good time to box in the lowers if not done already. Also, drill the holes for a sway bar if you don't have one but might want to add it later. I pressed mine out and then had them powder coated before installing the new bushings. I used a 2" x close NPT nipple and cap to install the new bushings in the axle.

Sounds like you're all set! The bushings that mount in the rear-end housing "ears" are the most difficult. The rest are "a walk in the park" compared to those two.

I've done this the easy way and the hard way. You're set up to do it the easy way, so take full advantage of it.

I've used a torch and had the rubber shoot out like a rocket. Luckily none of the burning rubber got on me. That stuff is like Napalm. It sticks and keeps on burning.

Make spacers for the arms when you're pressing the bushings out of them. This ensures that you won't collapse the arms.

If you want to box your rear arms, check the following link for good instructions: http://www.chevelles.com/techref/ftecref16.html

I got them out today graemlins/hurray.gif ,it wasn't hard at all.
i drilled out the rubber , then put them on a press with two spacers so i didn't crush the arms when i pressed them out , I just pessed them on one side till they were flush with they arms and they othere side were they stuck out it, i grabbed a claw hammer and pryed the out by the lip
i didn't want and pressed they all they way out on the press and take a chance of crushing the arms shape . now i will sandblast them box them and paint .thanks for all the good info. graemlins/thumbsup.gif
