good lube can be amber color or green or light brown or clear (syn lube) all stink to high heaven.
or black as tar, and full of shiny metal dust. ? bad news , 50k miles on GL5 is like max.
we take off top plug dip in finger, all its near the top but look here, it's tar like (think nasty old GL5) like 20 years old. old.
see?
the bearings have, there own grease and and inboard seal.
when the bearing failsm both seals are beat to death and both leak (talking 1 axle here) and then the GL5 runs the bearing now, as lube and leaks to brakes.
that is how it fails.
my guess it just too many miles on orig. koyo bearings.? or
or the grease long ago, just broke down, and killed the bearing, i'd bet this.
it's in fail mode now, and will only get worse.
new bearings and all new seals is the cure. (and the new lock ring)
i found them easy to change but again, my machine shop pressed them off then on for like $40.
so all i do is swap em. (my press is too small)
and sure rust , is possible, and that is never easy,,
