[s-cars] Driveshaft R&R writeup

[Tom Green]

There is a long nose grease fitting called a needle fitting(but it is  
a mighty big needle) available at the FLAPS.  I have used it to slip  
under rubber covers of ball joints after removing the wire clamp and  
for u-joints that don't have the zerk, but it isn't great there.  It  
will grease those Japanese fittings that just have the ball flush with
the surface.  I suppose that is what it is really made for.  The  
center bearing is sealed, but you wouldn't get much in there anyway.   
The only grease job mine has received is the front c/v joint where I  
am sure the exhaust heat is worst and really cooks the joint.  Taking  
the front joint down to clean out the old hard grease seemed like the  
thing to do, so it was not a problem to get grease in that joint.

That said, the long pointy fitting does help put some grease in tight  
places with minimal mess, and can be better than disassembling  
something like the center u-joint, because you might not get it back  
together.  :-)  You could probably do a good job if you were  
replacing the center bearing.
