I believe I crossthreaded one of my new upper ball joints (72 RR). It is completely seated (after much effort) and torqued to 120 ft/lbs. I didn't realize it was crossthreaded because it was such a pain to take old one out and I didn't think twice about it being difficult to screw new one in. So I just kept seating it (even though I knew they were prone to stripping/crossthreading!). But when the other ball joint went in easily, I then realized I may have crossthreaded the first one. Assuming this ball joint will never need to be replaced, am I OK -- or is a crossthreaded ball joint more likely to fail? It's seated level and torqued to 120 -- and I guess it's possible it wasn't crossthreaded. But I worry if threads were crossed it may be weakened or a problem/disaster waiting to happen. I'll yank UCA (it's 45 years old) and put in new arm and ball joint if I have to. But if crossthread is no big deal (other than if I ever need to remove it), then I'll not worry. Thanks for any advice.
