First odd... carefully look at the bearing rollers and outer race. Do you see any pitting, flaking dis-coloring? The inner race is hard to see damage..but..
To get an idea if the bearing assembly is likely good or bad..
Clean/Flush out the bearing on the axle and race then lightly oil it...say like 3 in 1 oil..
Then...Push the outer bearing race tight against the bearing cone and rotate the race back and forth on the cone ...is it flawlessly smooth or you feel some roughness?
Ant lumps or roughness if the bearing is really clean after doing the above probably means a bad bearing, (outer race, inner race or rollers).
Shown below is a real bad one off a 53 Plymouth Savoy wagon I once drove... it didn't make a lot of noise either!
Also a tiny pit in a quiet U-joint cross off a 56 Chrysler.. all bad things to see... All bearing surfaces have to be 100% perfect in appearance.
