If you do not see a Zert grease fitting then you do not grease it, as it is sealed for life, which is probably the case.
its located between the two shafts above the center support
It could have a carrier bearing but its pretty rare. I have a 96 firebird and it definitely has a split driveshaft. It is so rare that when my carrier bearing went bad, none of the part stores could even get a parts number to order one. So the car still sits. You will have to look at your driveshaft. If it's solid front to back it does not have a carrier bearing. If it looks like 2 shorter driveshafts that meet in the center of the car, then yes it would have a carrier bearing.
It could be a wheel bearing or the center carrier bearing of the driveshaft.
If you have a 2 piece driveshaft it could be the center carrier bearing.
its the center carrier bearing in the 2 peice driveshaft...have it replaced or go to a 1 peice driveshaft
I'm not sure what the question is, but I'll do my best to elaborate on the Center Support Bearing. Basically, it is a free-spinning bearing that keeps the driveshaft aligned properly. Without this bearing, the driveshaft will "wiggle" and knock around, possibly causing damage to the driveshaft's U-Joint. I've been told they are around $250 from Nissan.
70 inches is usually regarded as the absolute maximum length a driveshaft should be without adding a center support bearing
If it's a single piece driveshaft, remove the 4 bolts that hold the U joints to the differential pinion gear. If it's a 2 piece driveshaft, remove the 2 bolts that hold the center carrier bearing to the truck frame first.
it could be the center support bearing in your driveshaft
Simply unbolt the rear u-joint, the center bearing (if any) and pull it out.
Mark driveshaft and yoke to install in same location to maintain factory balance Remove 2 small "U" bolts from rear end yoke Pry driveshaft out of yoke Slide off spline from transmission not all drive shafts are one piece. How you remove the center support bearing(carrier bearing) from the forward drive shaft?
Center bearing should be replaceable after removing driveshaft
