Mikedog, this is for you since you asked me (plus anyone else that might find it usefull. Corey, if you want to make a write-up out of this then that's cool, I could take more pics since I have a bunch of old spare parts laying around.

Assuming the axle is already pulled...

Do you need to buy new parts. I have a new Timkin bearing which came with a small ring (retainer?) and got a timkin outer seal.

Quick questions on disassembly:

cut off ABS Rotor retainer
cut off ABS Rotor
remove snap ring

I know it is a good idea to, but do I need to replace all this ABS stuff or can I reuse it.

 

that last post was actually me under my brothers sig.....
I had a race shop (Michael Morris Racing) do mine for $30
I brought Micheal the bearing and seal and he pressed off the ABS rotor and retaining ring and reused them
