I noticed a few things while disassembling my front suspension and steering systems. First, I don't think any of my suspension components have been replaced - ever. Nothing has a zirk fitting, so I am assuming everything is original. Second, how many of these components can actually be rebuilt and reused? I see a lot of sorta kinda replacement parts and a few sources for bushes and ball joints, but are they any good? Third - It appears that the hubs and spindles for drum and disc brake front suspensions are the same - can anyone confirm that? Fourth - is there any insight or resources regarding how these parts were put together? I'm having a bit of a time trying to figure out how the ball joints in the steering linkage are pressed in to the various components. Finally, can anyone explain why the tie rod ends are motion restricted vs the inner tie rods? It's making my brain hurt...
