If you're talking about a 2 piece,remove the two bolts on the bracket then the four on the rear yoke. and then just simply pull the driveshaft back and out, it takes some prying or hammering but it should eventually come out, dont be surprised of tranny fluid comes out with it.

 

i meant from the bearing lol

 

Make sure you support the weight of the bearing and drive shaft. You do not want all the weight hanging on the tail of the tranny. Your rear does not have grease in it, it has Gear oil. It is more like 85w motor oil than it is like a grease. There is a fill hole on inside just about level with the Yoke in the rear housing.
