How is the universial joint greased? Is the only way to do this task is take the cap off and then hand pack it?
thanks for your time.

My 29 has a grease zerk at about the 5 o'clock position looking at the rear. I am told to pump in a half a tube of grease. If someone put it on 180 degrees turned, then the hole would be at about the 11 o'clock position accessible through the floor board.

There should be a grease fitting on the housing side that goes to the transmission. As stated if the housing was installed incorrectly the fitting may be on top.
 
The Model A u-joint does not have a grease zerk in the u-joint like a modern one. You have to pack the entire cavity with grease. As stated above, there is a zerk on the housing, use lots of grease.
 
I'm not sure I know just how much grease to add. If the zerk fitting just dumps grease into the shaft, then you could really go to town and pump all day !

Any rule of thumb on how much to add ?

Take the speedometer drive off the torque tube and pump grease in the u-joint housing until it starts to appear where you took the speedo drive off.
 
You can just take one (1) bolt out of the speedo drive and watch for the grease to appear that hole.

Dont be surprised if it takes an entire large tube of grease.

Mine did.

Crude way to grease the U joint but the original A nor the replacement do not have Spicer type U joints so there is no way to get the 4 bar greased except by packing the cavity.

A lot of the guys on the early V8 board use John Deere corn head grease for the u-joint housing. The stuff flows better than regular grease and seeks a level when its warmed up. After the motion stops it cools down quickly enough that it doesn't try to flow out anywhere (ie transmission or torque tube). You won't have to pump as much in there each time unless you are starting from overhaul empty. John Deere's web-site has a video of the stuff in action inside a corn header gearbox.

When I installed the ****** and rear end I hand packed the ujoint as much as I could during the assembly. Then when it was all together I used the tool kit grease gun. I had the speedometer gear off and pumped and refilled the small tool kit grease gun 10 times (or was it 12?) before it came out the speedometer gear opening.

My ****** has the original unsealed bearings and I had the top off the ******. Grease was just starting to show in the rear ****** bearing, when it was starting to come out of the speedometer gear opening.
