Im sure when you get to replacing the hubs at some point you will be pleasantly surprised at the similarity to other ford hubs. Im pretty sure even a few here having taken their for era 3's to ford dealer to get hubs done at a lower rate that what the stealership charges.

 

Can anyone direct us to videos showing DIY for replacing/rebuilding the 'air blocks'? It sounds pretty straightforward...

 

I don't have direct links, but I did some research on Youtube when I replaced mine. None were perfect IMO, but I figured it out. The rear was a pain, the others were relatively easy. Hope you have smaller hands for the rear though.

 

I used YouTube when learning how to rebuild the blocks. The front and the rear blocks are identical. Front is easy to get to and I would "train" on that one first. That way you will get a feel for the Voss connectors used on the airlines. Nothing difficult, just patience and time. Rear one is on the back driver strut tower and while visible (after the tire is off) the supply line and the rear left shock line are attached to the back of it, which makes it rather hard to get to them. I used a small flashlight wedged in close to the work area and a mechanic's mirror to see where to put the wrench. I don't have small hands, so it was essentially just wedging both arms in there and using my fingers to turn the 12mm wrench. Takes a lot if patience, but doable.

The rebuild itself is very simple. Four torx screws, open, clean, replace the o-rings, reassemble, reinstall.
