I got the lifetime warrantly ones from autozone, and i've considered it a curse. $60 an axle, free axles for life, but that means you get free lousy axles for life. I've gone through 8 autozone axles, and i don't drive harshly at ALL. Some of them have been broken from the moment i put them in, and others after a few months. I'm almost thinking next time they break i'm gonna bite the bullet and get some raxles or something.
