NOT on a 2000 to 2007 double row.
'08 introduced 25mm single row which are only 15mm wide, ( vs 21 mm for the double row.)
Apparently the first couple of years of the new bearings there was minimal grease in these newer cheaper bearings and they blew out with frightening regularity. Hence the 30 K replacement recommendation.

Well engineered wheel bearings with the right grease and proper installation should last indefinitely. Unfortunately, Harley's and a lot of other vehicles only get the proper installation; not much you can do about the engineering, but even on sealed bearings I often clean them out and put a top quality synthetic grease in them; can make a huge difference. Ball bearings just suck for wheel bearings, but if they're cheaper to make, we'll have to live with them.
