The right side A arm is off the car. Cleaned up many years of grease, grim, and overspray. It physically doesn't look too bad. I can't detect any cracks in it. The spring seat looks good, just needs painting.

I was able to get the fulcrum cotter pin nut off the bottom with no problem. However I can't see a way to get the pin itself extracted. What's the best way to do that? I've been soaking it in PB blaster from the underside for about 10 minutes.

I may well be wasting my time with the A arm. I'm able to take the kingpin and wiggle it around. I can see the fulcrum moving around in the rear bushing.
 
yep, no good. Needs new bushing brazed in. Someone does that,?????????????
 
I was afraid of that. Not sure who brazes them here locally. It would be great to find someone who could do than spend a leg trying to buy new arms.
 
New are not necessary, someone will be along to tell us who repairs the A frames.
 
I was able to drift the cotter pin out without too much hassle, and now have the fulcrum out. It still doesn't look too bad, though an icky redish brown color. There's still threads/rifling in the bushings.
 
Hears how it works. The pin does not wear much the A frame threaded area does. The pin turns on the threads and wears them out. That icky brown stuff is powder worn from the A Frame bushing and it has rusted. One more reason to grease them a lot. er often. A grease fitting both front and rear is a good idea even.

There should be no side to side wobble at all.
 
I've heard about adding another grease fitting to the other side. How is that accomplished?
 
Drill and a tap. Understand PeterC can get the A frame bushings redone and they come back with two zerks.
 
I had the exact same issue when I installed the major suspension kit on my Midget. I purchased two rebuilt arms from Apple Hydraulics in New York. $95 each and a $75 each core. After speaking with the fellow at Apple he asked that I did not try to remove the lower fulcrum pin or Kingpin and he would do that.
Arms arrived quickly and fit perfectly.
