remember - you get what you pay for.
To actually fix this, I'd try a die first. You'll need a big bench vice to hold the joint securely, and you'll need a die for whatever size threads & pitch the joints are. Get a Grade 5 nut for testing the threads.
Also get a Grade 5 bolt to test the threads in the arm, and make sure the threads inside aren't jacked up. If they are, you'll need a tap at the very least, possibly a new arm.
Keep in mind a die will run around $50 or so. Don't cheap out and get some HF crappo die, or you'll make things even worse. Get a good Irwin/Hanson die. You also need to make sure you have a die handle to grab it, if it doesn't have flats on it. if it does have flats on it, make sure you have an adjustable wrench big enough to grab it. die handles are better because they provide a more even application of torque, but they're also expensive.
If you need to chase the internal threads, the tap will also run $50 or more. When using a tap, you really need a t-handle. Big t-handles for taps in the 1"+ range a quite expensive.
Make sure to use cutting oil (3-in-1 is fine).
