@ ~70K miles, BOTH my front wheel bearings started humming. I replaced them myself with OEM bearings and flanges. Not a tough job really. Took 3 hours each side. I bet i could do it quicker now.


Now, at 113K miles, I *Think* i hear them starting to make noise again. I can definitely feel it when i turn. I guess i'll have to pull the rotors off and check as that was the only way I could feel that they were bad before.

But c'mon...really? Wheel bearings again?

 

I am at 107k and I am pretty sure that my front bearings are on their way out. I guess I am lucky? I noticed there is a speed-related hum that is not brake related, or alignment related. Also, noticed the car is a bit unsettled immediately after bumps on the road.

 

160k on stock bearings. I have an 05, what year is your car? Just wondering if it is year related.

 

I've seen it happen due to being pressed in incorrectly. Not accusing, just saying. Did you use a press? Where did you brace the bearing while pressing the hub in?

 

Its like compression rods. So people need to replace them every 30k and some people hardly have issues.

I'm used to wheel bearings going every 100k miles or so. i'm @ 75k and my fronts seem good.

 

I was thinking it might be related to the aggressive pads on the early sedans. Additional heat from the smaller rotors being transferred to bearings and breaking down grease faster. Just a thought.

 

had mine replaced at 165,000 and it was only driver side. now I'm at 170k car drives like new.

I'm not exactly sure it's my bearings just yet. I was at 90MPH on my ride in today on some fresh pavement and the car was silent. So who knows. I know i hear something in my turns, but my tires are nearing the end of their life so it could be related to tire age/wear.

So i could be good for a while longer. Not sure. My car's an 06, and when i did my bearings i used OEM bearings and hubs and pressed them per the FSM to the lb-f given in the manual by pressing on the center race and hub (to keep the force off the bearings). I'm pretty meticulous about that.

Just drive and see what happens i guess

 

same boat dude. replaced both sides at 140k km and now at 195k km i hear the noise again. i just spent money on brakes and now this? still love the car though.

 

My tires hum at 60+ firestone FR710. I got them cheap for a winter set so i'll live with it.

I know you had them DWS. not sure if they are known to hum.

 

They don't really hum, but if i take a turn, i can hear a grown/scuffing from both sides. Louder with window down.

BUT, on a straight smooth road, perfectly quiet. When my bearings failed the last time, i could hear them humming over 45MPH. The other day i shifted into nuetral (to eliminate engine noise vibration) at 80MPH on fresh blacktop and it rode silent.

So i'll just wait and see. It's getting cold, so i'm not replacing anything right now

I have 45K miles on the Continental DWS....probably 40% tread still left. I might make 60K on a set of tires which would be awesome. I'd buy again as they were awesome in the snow as well

 

As you know the classic symptom of a worn bearing is hum at highway speed. If yours is AWD model, then it could very well be the front drive shafts. When the shafts go bad, they make loud noise when turning. Check it out.

 

I'll check it out this weekend. I have an oil change to do. I'll check out the shafts. Hell...those seem like less work than wheel bearings.

 

Running a 2004 AWD Sedan 130k and noticed the hum about 5000 miles ago. No noise when cornering, or taking an expressway on/off ramp but it�s been progressively getting louder. As the noise got more pronounced I realized that it is definitely the front end, but is still very difficult to determine the side. I figured a bad bearing must be producing heat resulting from the excess friction. I drive about 60 miles to and from work a day. When I got home on two separate occasions, I laid on my back next to the wheels , reached in and checked the all four axles as close to the spindle as possible. If your fingers are skinny enough you can get even closer to the center of the shaft where it meets the spindle but mostly I just wrapped my hand around toothed area. I assume that is the end of the CV joint. It�s around 30-40 degrees outside and three of the points were cold. (Probably at air temperature) The passenger front was warm to the touch. I would say a 25 to 35 degree difference in temperature. I feel pretty confident that it�s the passenger front bearing that is going bad. This will be a DIY for me in the next week or so. I just bought the car, less than a year ago so this is the first bearing change for me.

I would suggest using caution with this method as I don�t know how hot this area could get with a really bad bearing.

Hope this helps someone.

 

Got other the car the other day. Everything looked fine. I pulled my rotors off and spun the hubs and they were quiet, so pretty sure my wheels bearings are fine for now. In the past, the only way I could tell they were bad was to pull the rotors off and spin the hubs. Only then could I feel the roughness.


I'm no stranger to bearings. I did this write-up a couple years ago.
