Curious what methods you use to remove ball joints.

I tried a new, homemade puller. 3/8 ‐24 rod coupling welded to some all thread. Two nuts, one of them welded on. A heavy plate washer and a piece of 1.5" conduit

I install the puller, put some tension on it, then heat up the bottom of the strut.

After a couple mins of heat, I hear a few pops and the joints came out pretty easy

New joints were kept in the freezer awhile. I heat the strut, squirt some wd40 on the frozen ball joint, and push it in by hand. One the temps equalize, it fits in there nice and tight.

Similar, but reusable - I use a 3/4" threaded rod drilled and tapped to thread onto the ball joint, a length of 7/8" ID steel tubing and thick 3/4" inch flat washer - basically the same set up as you created, but a bit more versatile - I can screw an inch long piece of threaded rod into the end of the 3/4 inch rod that was previously drilled and tapped and attach thread reducing couplings to extract different size ball joints.

Here's a pic of the banjo fitting adapter I put together to use a grease gun to pump stuck pistons out of calipers and master cylinders. I also have an adapter to fit inverted flare line fittings for the same purpose.

No one has a patent on creativity and your puller is as good as any.

My first attempt failed at the weld between all thread and rod coupling. It was a nice looking weld but, that didn't matter.

2nd attempt is a really ugly weld. I burnt thru the rod coupling and just puddled weld material on. It worked.

If that failed, attempt # 3 was drill and tap. Wish I had a drill press.

Brilliant!
