G'mornin',

There is a tool.....Tap Extractor.....however I don't own one, and I am unsure if it will grab your "Rethreading Tap".....

Rethreading taps are a bit different from your usual "Machine Taps".....they are designed to do just what their name says.....rethread.....or chase and clean up old threads without removing any extra material......I own a set that I purchased from MAC.....Snap-On has a good set as well.....

Note, my set has 3 different M12 taps, different thread pitch, my car required M12x1.5





I've owned my rethread set for some 10 years, and have one broken Tap....1/4" 20 NC.....it snapped along the shaft between the hex and the barrell shaped cutting head.....I think I got that out with some needle nose pliers, patience, anti-anxiety drugs, and if you screw your mouth up just right....

Personally, at this point, I would look for a used steering knuckle and replace ...
