Front Wheel Bearing change on a 240D

[Nikolas]

am the original owner of a pristine 1982 240D. Through the years I performed most all the maintenance by myself. I believe this particular automobile is the last of it's kind and even though the factory in Stuttgart would offer a brand new one in exchange for it, I would never let her go for any amount of money or a "new one" She is Texas girl, but now she lives in a Island between Italy and Greece were you must know what to do and how to do it.
I need to replace the front wheel bearings. I have everything that I need. New German bearings, Liqui-Molly bearing grease, Harbor Freight bearing extractor set, machinist's portable dial (inches) and the magnetic base needed for the dial. I have tried to read just about any answer I could find in this forum on the subject. I do not know how to use effectively the magnetic base and dial. Is there someone that could direct me step by step on how to do it correctly and on the first try. I am as you could say, mechanically very inclined and I only need to be shown once. You see, here there aren't the right kind of shops to take your pride and joy in case of an error. Things have to be shipped in from the States and at pretty good penny at that, and in case of an error...well...good luck. It has to go out of the Island. Anyway, if someone can provide the help needed, Helga and I would very much appreciate it. By the way, we will be coming home soon.
