Hello! I'm still shaking down my 1970 MGB that I bought from Dad. One local enthusiast said I should re-grease the front wheel bearings (who knows when that was last done). I'm doing some research on that and I'm trying to decide if I should re-grease them or just replace them while I'm at it. I found some instructions on their replacement, but nothing on just re-greasing. How much more difficult is it to replace them than to clean and grease them? Replacing them requires quite a bit of disassembly from what I see, and I'm not very mechanical (yet) -- but it looks like I have to remove them to re-grease them, anyway? Any advice? Thanks!
