So I just diagnosed a bad cv joint in my front driveshaft and was looking on ebay for a replacement. This one has u-joints on both ends wich I much prefer but I just wanted to check and make sure this would fit and that there isn't some special reason for the cv joint?

CV helps with vibrations. Not always necessary. CV helps with angles. Divides a large angle into two smaller angles. Saves u joints and reduces vibration. Not always necessary.
I've used them on big 4x4's front and rear.
Single u joint is stronger than a CV.
