Hi Guy's,



Pulled the rear axle out the other day to replace the "Foreign Shackel's". I had filled the U-joint housing thru the grease fitting..Somebody said the fitting was to only grease the clam shell,,,



I must say the grease was coming out of the U-joint "housing" pretty good,,, The drive shalf area was packed full of grease...



I'am thinking as the U-joint goe's around it throw's grease everywhere..Now where did that idea that the fitting isn't for the U-joint come from ?.

I remember the same discussion / argument, All I can say is based on the location of the grease fitting it is apparent to me that it was intended to lubricate the u-joint primarily and possibly the clamshell passively. (The clamshell, brake components, battery, muffler bearing are all lubricated by Fords patented "passive chassis lubrication system" - known to some as a rear main bearing leak)
 
I cannot find any specific directions for U joint lubrication in the service bulletins for Model A or the Owners Manual. However, the 1932 Service Bulletins for Model B's (and common sense) says to "fill the U joint housing" with grease. I always pack it with close to 1# of grease when installing it. I pack most of the rest of the pound into the torque tube. Once its all assembled, I use the grease gun to top it off. If you remove the rear speedometer housing bolt prior to greasing the U joint, you will know you have filled it when using a grease gun when the grease begins to come out the bolt hole.
 
Ditto what Pat said.

The same clamshell grease zerk also lubricates the inner ball socket on the 1928 brakes with the split shaft. There is a groove cut into one half of the clamshell which leads to the socket supports.
