Wow, those look pretty bad. I've never seen needles broken like that, but the 
center part between bearings looks rusty. Someone left this front end without 
grease for a long time. I assume that was before you. This is a good lesson for 
everyone to keep grease in their front axle beam. I'm afraid that a lot of 
these die simply because mechanics don't notice the 2 upper Zerk fittings. 

Every type 3 has FOUR (4!) grease fittings on the front axle.

The spacing between inner and outer bearings changed at some point in the early 
history. The inner bearing is a metal sleeve bearing set in a fiber ring. The 
fiber ring was not supposed to be replacable. I don't even think I've managed 
to save any of them from axles I've parted out. I probably have a sleeve 
bearing, however. 

Early and late upper swing arms are different because of the different spacing 
between bearings, but I've heard of people repositioning the fiber and metal 
sleeves in order to replace these arms. I MAY have a good late arm.

Most of the servicing of this is covered very nicely in the Bentley manual, 
including the dimensions for the driver to install the bearings.
