 A ball joint. Super duties with that many miles, you more than likely are ready to rebuild some stuff in the front end. Yeah, the U-joints in the end of those axles, they will bind up, and if they're in the right position, yeah, they'll be really tough to turn or straighten out. Because you're still working with a solid front axle on there, and the ball joints, they eventually get pretty rough. Jody, thanks very much for the call. Good luck. We'll be back. We're going to take a quick break. You're listening to the Under the Hood Show.
