How do I grease the center ball? I cant find anyway to do it online.

 

or can I not grease it?

 

Does it have a fitting? Mine does and it's a royal bitch to get to. I almost have to take the shaft out to grease it.

 

Hi, you cannot grease the center bearing (ball) without taking the final flange UJ apart. Then you can get access to put in a dollop of grease but be sure to use high pressure, high melting point grease like Castrol LM or equivalent.
