just replaced both hubs yesterday,before reading second post.
i got seals with the hubs but didn't see where they went
guy at store said might be axle seals....oh well i didn't install them
didn't think i needed them.
thought they were sealed,didn't grease them either.
did i f 'up.???
real simple to replace -didn't need to remove strut bolts...
hubs came out with a whack from a bfh...
car drove ok and noise was gone afterward...
post back if i f' d up without greasing them.
