The lower and the upper both have crown nuts on them, one is bigger than the other but I don't remember the sizes or which is which

Mine was 1 1/8". You'll need a 22mm for the upper IIRC and the 3 hub bolts require 12pt socket.

The 3 hub bolts are usually rusted so bad that the 12 point socket turns on them, I ended up hammering on a 6 point after heating them with a small propane torch for about 4 minutes each. Trust me, you do not want to skip the heat, it makes every one of these bolts turn much more nicely and is key. You want to heat the part where the threads are in the hub. Then, replace the bolts once you have the old ones out.
