A-arm ball joint threads

[cjtl1000r]

I need to run a die down the threads to clean them up but don't know what size they are. Any help?

ive had to do this three times. you can take them to o-reilleys or something and have the threads measured. what i usually do is hold the shaft with some vice grips, take the castle nuts, and run them up and down with an impact. keep doing that until you can run them down with your hands. there will be a couple rough spots, but it will hold. blow out any shavings and spray wd40.
