Not wheel bearings but rather flange bearings, on mine I saw mangled chunks of metal hanging in the grease when I changed the rear tire. No symptoms whatsoever. The pair of bearings are standard 6905RS bearings available anywhere. What it looked like cleaned up.

So looking at the 2002-2008 VTX1800C/F service manual per page 14-7, the diagram at bottom indicates to replace 3 bearings
1. Final Driven Flange A bearing (6905 RS) with new O-ring
2. Bearing (6304UU)
3. bearing (20 x 47 x 20.6mm) = 5204-2RS Sealed Ball Bearing, 20x47x20.6 (Double row)
3. Dust seal
5. Brake Disc bolts
In post #11 above, Enduro mentions a pair of 6905RS bearings. Is that in a 1300 ?
1300 and 1800 Bottom right corner of the PDF shows cut open view,
you can see double 6905RS bearings.
That doesn't seem right according to 1800 pic attached.
Would it not be a good idea to buy double seal bearings to keep crap out ?
I should have spent 30 minutes with a brake cylinder hone to get the light press in on the driven flange,
I used a 5/8" bolt and the bearing stack tilted some on install. I had to correct that. My vise would have done better,
How do you know if the bearings are GOOD? Put your finger(s) on the inner race and twist back and forth.
Remove flange, insert favorite finger into inner race, and spin the unit. Anything but smooth turning is bad...
That double row ball bearing here in San Diego from Kaman bearing - Koyo brand - $54 for one ......wow expensive.....however I have seen other brands for cheaper....
The 6905 & 6304 are reasonable.....
When I build them I use 6905-2RS (double sealed) and yes there are 2 - stacked together. Look on Fiche for actual part #s of other bearings. I use a Honda bearing for the flange but it's not on the fiche. If you want the part # send me a pm
