There is nothing else that needs to be done that I know of. Any lubrication remains on it's original schedule. I would guess since the spline shaft is regularly greased and is free to rotate in the Clary hubs then there should be no reason to try to lube the sealed ball bearings. I've always heard them referred to as Clary Hubs.
Here's a short blurp on them from the G503 by Joel:
Clary Hubs

ORDNANCE STOCK NO. G-740-8327042 times two will get you a set of two. They are simple to install and require the reuse of your old WO-800798 Hub Cap. There are two types pictured, the larger Clary Flange is for the M-37. Note the A-868 Drive Flange that you will have to remove. This particular one is from one of the last new CJ-5 Jeeps we sold, the drive flanges were removed to install Warn Hubs. The small ring next to the hubcap is a spacer to be used when installing the flanges on the MB/GPW. The ends of the Outer Axle Shafts rest inside shielded ball bearings, the flanges are cast aluminum.
CLARY FLANGES were manufactured under Gov't Contract DA-04-200-ORD-448 by the CAM TOOL CO. Oakland CA. What is unique is tht the M-38/M-38A1 Flanges and the M-37 Flanges I have were manufactured under the same contract and were both packaged during 11/55.
ORD PART NO FOR M-38/M-38A1 is G-740-8327042
ORD PART NO. FOR THE M-37/WC is G-741-8327043
If you do install a set of these critters, be sure to pack your original drive flanges in your Jeep Storage compartment. I can't think of a better use for these GI Issue flanges than to take them along on the ALCAN trip, they might make a bit of difference due to the great distance traveled.
Note the Script "F" on the NOS O.D. Hub Cap, these were plentiful back 30 or so years ago when the wholesalers had a "Glut" of them.
Should you have a set of Clary hubs that do not have sealed ball bearings then I would mak sure they are lubed.
Generally speaking an open bearing is a non-sealed bearing. A covered bearing with at least one grease port/path is a shielded bearing and a fully enclosed bearing is a sealed bearing. Here's a quick explanation:
Simply put, if you can see the ends of the rollers or the side of the balls it is not a sealed bearing. I really can't tell in your photos.
The largest bearing above is not a sealed bearing.
Gary,
I reduced the file size of your photos because they take up too much band width and are difficult for folks to view who have slow download speeds or small screen devices. Back in 2014 I postsed a "How To Post Photos" article on our photo album's help page. In that post I highlighted a 250K photo size posting limit. http://www.willysmjeeps.com/v2/modules. ... pic&t=8670
