How bad can a front CV driveshaft joint get before it is unusable. I know you can replace the u-joints in it but I'm talking about the Ball/pivot point. Or can you always rebuild them. The old guy at the driveshaft shop says that they can't be rebuilt. Luckily I have another shaft. The CV in it seems to be ok. I'm going to check the Joints, Re-grease it and install it.
