On the road, about 600 miles from home (on a weekend of course), don't have my Chilton or Haynes manual with me...sitting at a hotel overnight contemplating how fast and how long I'm going to drive on the interstate tomorrow. At least it's only me this time. Left the wife/kids home for this trip.
'05 Vibe Base, 165K+, A/T.
Started noticing a growling noise a few hundred miles ago (when there weren't any radio stations around, kinda quiet in the car). A decent growl from the front end. Starts when the car starts moving, doesn't change with gear changes at a steady speed, only changes frequency with road speed, gets real quiet on a right hand curve, get a bit louder on a left hand curve. Figure it's the front/right wheel bearing. Doesn't pull either direction, very very slight shimmy @ 75MPH+ (enough to make the remote start antenna vibrate a little and that's it), but I'm also due for a wheel rotation.
Far as I know, the car has spent all it's life up north (great...probably rusted/welded itself together if it's set up like I think it probably is). Don't remember what it looks like in there when I was changing struts last year.
Is it a hub/bearing assembly that bolts up to the steering knuckle such that I have to remove the knuckle like I was going to change struts, and pop the lower ball joint, and axle. Then either press out the hub/bearing myself or get a shop to do it?
Or is it all one whole piece where a guy has to swap out the whole knuckle/hub/bearing as a single unit, and while you're in there may as well change out the lower ball joint and whatever else gets wear & tear? (which actually sounds a fair amount easier)...
