Just to clarify, you are replacing either the entire driveshaft or the universal joints for it slipping to neutral on the highway?
If this is the case, I doubt the drive shaft is the issue. However, here is all the info on what you asked for on the U-Joints. You do not need to replace the entire shaft if the joints are an issue but it is much easier to replace it.
Let me know if I am not understanding something and we can go from there. Thanks
