not really following you there but if it's mysterious squeak that seems untraceble it maybe be your ball joint. those were exact symptoms on one of my cars.. the ball joint actually sheared off one day... if you press on the hood area and it does the squeak check that. if the ball joinst have no grease fittings and have not been repacked then i bet you're due... pretty simple job... upper is cheap. lower way more...
some of the other questions can be answered if you look just a bit lower in this forum...
also use the search engine to look for cv axles and rotors... related disassembly info...
as to repacking itself... i normally put a chunk of grease in the palm of my hand and then press the bearing into the greae till the grease comes out the ends, rotating to another spot when finished. i tend to shove more grease from the end too. then smear a bit on the races and place the bearing in...
