There are some decent products out there for taking care of the splines and drive shaft but i use Guard Dog as it is specifically designed for our use. With Guard dog, I'd use 570 on the splines and Guarddog 525 on the drive shaft and you will be a happy camper. Don't forget to change out the "O" Rings as mentioned in Shop Talk. No connection to GuardDog, simply a great product that many of us use.

Good luck...
