[jgkrenton at comcast.net]

All: 



There is a pretty good discription of the job here.

Seems to be some u-tube video out there too. 



FYI 



Jeff kimball  #2467 who's done this job on several cars now...   Go slow and careful!

You did misunderstand me completely Boyd. What made you think I was doing it 
on the car? I used a 30 ton press in my shop. 

There is a nice clean, easy way to do this job. You need some tools, some 
time and patience. 
Someday when I have more time, I'll get the photos and story together and 
present it. 
I still think there are others that have done it too.

  David, 
   B.Seib is apparently talking about talking about trying to remove the 
bushings while the a-arms are still on the car. Personally I can't imagine 
even attempting that. I removed the a-arms  and as I said used a torch to 
burn out the rubber busing ( after cutting of one flange) I put the a-arm in 
a large vise while cutting of the flange ,I also did some with an air 
chisel. The rubber seems to play a large part in holding the bushing in 
place so burning it out made removing the rest of the metal much easier. 
Once one end was either cut off or chiseled off and the rubber burned out 
one person held the a-arm on an anvil and the other person used the home 
made tool to hammer out the the remaining metal of the bushing. Some of the 
popped  of relatively easily with the pneumatic chisel while the others took 
Herculean effort to remove. So don't think your doing something wrong it is 
not an easy job. If someone were really "smarter" they would send the a-arms 
out to a shop to be done!

    Hi David 

    If you are talking about the factory rubber bushings with steel outer 
    casings in the control arms, they are pretty tricky to remove, as you 
are 
    now aware. There is a rather involved process of very carefully cutting 
the 
    largest outer bushing flange off. I recall making a special tool using a 
    hole saw to do this. You still need to be careful not to damage the 
control 
    arm while cutting through the flange. After the flange is machined of 
with 
    the hole saw, you should be able to back the arm up with a piece of tube 
and 
    press the bush out. Others may have developed other better methods of 
doing 
    this job. I suggest you wait until you get details before you remove 
these 
    bushings or you might damage the arms. Heat may help light the rubber on 
    fire, but I doubt it will help get these particular bushings loose. 
Maybe 
    I'm missing something ? Control arms can cost money and are not always 
easy 
    to find... 

    If you're not sure, wait until one of the smarter guys answers. If they 
    don't, I'll take some photos of my own method for you.

    Can anyone lend some ideas on how to extract the extension bushings from 
all 
    the 
    suspension arms?   I have welded up a jig with a piece of iron pipe that 
is 
    just 
    large enough to clear the largest diameter steel flange on the bushings, 
but 
    given that all the bushing ends can only be supported on one side in a 
    press, 
    and the bushings are taking about 4 tons of pressure to get out 
(according 
    to 
    the gauge on the press for the two I managed to extract),  I am having a 
    heck of 
    a time.   I've used penetrating oil and have not yet resorted to heat, 
but 
    the 
    real challenge is holding the arm in a level position from only one side 
    without 
    bending it. 


    Thanks 

    David
