Argh! What is this?!
Okay, I'm trying to figure out what a particular part on my truck is called. The CV joint on the TIRE side attaches into the.. well the tire-thing rotor? Anyways, the part where the splines actually meet the tire side's actually broken off and spins loosely, so if I attach the CV joint the way you're supposed to it just spins freely. What's up with that?
