I am hearing a rhythmic (but very slight) noise in my front end (I think). Sounds like a bearing to me. But could it be a CV joint problem? I started my working life as an auto mechanic, but very long ago in the 1960's decade. How much trouble is it to change the bearings in the front hubs? Can an old goat like me get'er done. I used to do plenty of wheel bearing changes back in the day. Is it any different? Using a drift pin punch and a hammer to get the races/seals out/in?
