Rebuilding Aisin Manual Hubs

When I first got my 4Runner, I had to lock/unlock the hubs with pliers because it was too difficult to turn by hand.  I figured a hub rebuild was in order.  There are several excellent write ups on the internet for Toyota Aisin hubs.  Here are some links:

Off-Road.com

After following procedures from the above links, my hub dial now turns freely with ease.  When I disassembled my hubs, they were bone dry and there was lots of surface rust.  I cleaned everything up and applied a light coat of grease.  Here is what they looked like


 
 

Nice rust on the inside which was making the dial hard to turn

 
 

 
 

More rusty surfaces

 
 

 
 

All covered in rust

 
 

 
 

Did I mention the rust?
