WELL, in the last three days it got a lot worse right? I would not go on any long trips right now. As far as noise going away when turning if you turned right and noise is gone then it is the right side since on a right turn you have unloaded the right bearing and transferred most of the load to the left wheel. And vice versa. If anyone wonders if it is just noise from tires here is a trick I used to use in the dealerships. Inflated tires to 45 to 50 PSI and drive a short distance to see if noise is dimished. If it is the noise is from irregular tread wear. By upping the pressure the tire is now running on the center of tread and the worn edges are not touching the pavement. DO NOT forget to lower pressures when you are done. Although the rough ride might remind you.

Yeah, it'* towards the right that it gets quieter. But I can clearly hear the noise on the passenger side, so at least it'* not a question of which one is bad.

It has gotten much louder in 3 days, and I drive a lot. My commute to and from work IS a long trip I drive 90 miles a day/450 miles a week. I won't even have the money to replace it until next Friday. Even then it may be tough.

I may drive my other car for the time being.

though it'* not registered or insured.

BCA brand from Advance. I'm guessing this is the best one? I won't get anything from AutoZone. It'* $144 though. Not what I wanted to spend, though reasonable.

Right, If you hear the Hummmm while turning towards the left, then your right (passenger side) wheel bearing is bad. I believe you can safely drive this car another week. My personal rule of thumb, if the radio can drown out the noise, it'* safe to drive. Don't drive an uninsured/unregistered car.

I can drown out the noise, but my subs will have to be thumping HARD.

I'll see how it goes tomorrow. I won't be driving my other car.

I have never heard of anyone here (or there) having a catastrophic wheel bearing failure. Of course, I don't want to hear you being the first. I've driven over well over 1,000 miles with a bad wheel bearing in the past (before I replaced it) and this was without a subwoofer

Default same issue here

I have had the same issue happen to mine (92)...i.e. constant loud hum, would go away when I turned one direction or louder in the opposite. Drove it like that forever (at least 10k) . I replaced the wheel hub bearing (pain in the butt) . When I looked at the old one, I couldn't see any obvious damage to the bearings. Sound went away, drove like a champ. Now, 6 months later, the exact same sound is coming from the same wheel. put new tires on (needed it) but no luck. Could it be anything else? Could the UV joint be a culpret?

If it'* the same exact sound, with the same symptoms when turning the wheel, I'd say it'* the bearing again. How many miles have you driven in 6 months? What brand of hub bearing did you get?

I would say around 25k. I bought it at a place called Wright Auto Parts...not sure of the manufact. Part cost 120. Is there anything that could be contributing to its premature failure? and what manufact do you recommend?

Sorry to hear that you need to replace the same wheel bearing. $hit happens and it happened to my former Olds a couple of years ago. I had to replace my right wheel bearing twice within about a year. I have no idea what could cause the premature failure. Just my bad luck, I guess. I don't know the mfg of either wheel bearing but I did not get the same one (mfg) twice. :(
