Sorry, but I don't know what parts you would need. I've never taken apart a front axle.
I've got a question though - Forgive my ignorance, but how often are we supposed to take these things apart, clean and grease them?
I'm generally religious about preventative maintenence. I've changed the fluids in the diffs of everything I've owned, and I replaced wheel bearings years and years ago on a trailer.. But I've never re-greased axle bearings on my trucks. I don't put them under water. Everything I've taken apart was still in good shape.
Your story has inspired me to pull all mine apart this summer and check them out. Thanks for the great thread.
