Subject: rear wheel Bearing grease

I've got what appears to be bearing grease oozing out from the rear
wheel (on an Eldo) where the spindle meets the hub cover on the left,
and from behind the spindle nut on the right. I only noticed recently
after a 200 mi ride. Does this mean both seals have failed at the same
time...or is a little oozing considered normal after a lengthy ride?...
thanks in advance for any advice... Bill
