I ordered new urethane upper and lower control arm bushings. I have full access to hydraulic presses at the machine shop. So what kind of nightmare am I looking at to replace them? Any tricks to getting the old ones out and to get the new ones in? I'm going to glass bead both uppers and lowers while they are out and repaint after the bushings are in. Any info will be appreciated.

I guess you mean the fronts.

To get the lowers out I just took a shop hammer and a big chisel and crushed/cut them out with the control arm laying on a block of wood. Of course you have to get the old rubber out of the shell first. A few holes through the rubber with a 3/8" drill worked great.

To get the uppers out I used a tip from a fellow TCer. An air hammer. "Vibrated" them out in about 20 seconds each. It wouldn't work on my lowers though. Those suckers were in there.

For installation I cleaned up the holes with emery cloth. I then cut some "jigs" from a length of old 2" exhaust pipe. I split the pipe in half and cut pieces to fit between each opening so the control arm wouldn't be bent when I pounded the new sleeves in place.

I have presses too, but it was easier to hammer the new sleeves in place with a block of wood on them than to set up the press for it.

I got mine out with a cutting torch.
Must be careful to not nick the A frames though.
Put them in with a large bench vise and a spacer to go in between the sides of the Aframe.

Easiest way is to LEAVE THE SHELLS IN THE CONTROLL ARMS. Remove the rubber insert and the center sleeve by burning the rubber with a torch. Install the Poly bushings with new center sleeves into the original shells after you've cleaned them up. No press, no distortion, no problem.

Drill the rubber out with a drill bit and then knock it out. Then, assemble a hacksaw with the blade passing through the hole and cut the surrounding metal sleeve. The sleeve then will come out easy. It is a lot of work but not particularly difficult, just time consuming.

Ken,

All of the ways listed here will work as I have at one time or another performed some variation of these acts. On the last set I replaced I bit the bullet and got an actual set of Blocks and the C-Clamp Press that is designed for bushing removal.

It took me about 20 minutes to take all the old bushings and the ball joints out and about 30 minutes to put them all back in. See if you have a buddy that has these tools he can loan you. The right tools make all the difference in the world.

Good Luck,

Bill

The lowers will pop right out if you support the arm in a vise opened far enough to let the bushing drop through and hit it with a BFH from the inside. I recently did a 64 Chevelle and it took about 2 minutes to get the bushings out. I worked my way through college at Auto Suspension Company in Phoenix in the 1970's when almost all cars had suspensions like these.
