Time for new wheel bearings?

I've had my 03 SVT for a little over 2 years now and after putting 50k miles on it, I think it's time for some new wheel bearings. I recorded a video a little ago of the noise I believe is being created by them going bad. I thought it was from my old SVT 5 spokes being bent but after putting on a brand new set today, the noise is still there, so I suspect the bearings.

Here's the vid. I'll be jacking it up on thursday to do the usual bearing checks but figured I'd get some other opinions as well.

Can't tell what noise you are referring to.
The only "noise" I heard was a clunking that sounded like bad end links.

One of the first symptoms of bad wheel bearings is low speed brake squeal that changes as you make mild turns.

I think he's referring to the loud humming sound. I can't really say what it is, because the bearings I had to replace growled when turning. I'm not sure what they would have progressed to had I not changed them then...

The clunking would be bad end links...bearings would make a constant noise.

I should have been more clear. The sound im talking about is the constant humming throughout the vid. The clunking sound was me going over a bridge lol. The humming sound starts out as a low growl at low speeds and becomes a steady hum once I get up to speed. I noticed when I turn my wheel to the right enough (mainly when getting off the highway on exit ramps) the sound will go away.

Your typed description in the last post makes it sound like wheel bearings.

Had one of these go out on a road trip, not a fun 300mi trip lol you'll feel a vibration in the steering wheel (possibly vibration in the whole car) and an annoying humming at anything over 20 mph. I would get it replaced asap.

I just got done doing some inspecting and none of the wheels had any play in them at all. I drove around my dealerships lot and its definitely a prominent growling noise in the rear, even at low speeds. So to recap, its a growling noise at low speeds and as I gradually gain speed, it becomes a hum.

Even with no play in the wheels, I still think its my bearings but I definitely don't want to just go throw parts at this thing. Are there any other tests I could do myself?

Put the car up on stands.
Remove: wheel, caliper, rotor.

Rotate the hub, if it is anything other than smooth with slight and even resistance, it's worn. It's not like a worn wheel bearing lets the wheel flop around noticeably, it's more like a couple minutes of angle. By the time you hear growling, or can feel slop with the wheel attached, it's not just worn out but self destructing.

Or, go to a parking lot:

10 mph sweeping turns in both directions, if the noise changes at all*, it's the wheel bearings.

* change from going straight, vs turning in either direction.


Or you can just wait until it chews itself up more and the symptoms become unmistakable, and further damage may occur.

Just from reading that, I'm almost positive it's my bearings then since it does go away when im turning right. I haven't paid attention if it goes away when I turn left or not. That I'll have to check out.
