pulsating noise - bad wheel bearings?

i've been noticing some whirling/pulsating noise coming from the right side of the car recently, within the last week or so. the noise varies depending on speed, but doesn't start until at least 25mph. it is only this pulsating noise that increases with speed, no clunking or anything else.

i'm having trouble figuring out of it's from the front or rear, but my friend sat in the passenger side and thought it seemed to be coming from the rear. however, he was unfamiliar with the normal sounds and road noises from inside the car.

i've checked that the tire pressures are correct and there is not visible tire damage.
my friend and i also jacked up the car and spun the wheels, and all 4 seem to be rotating smoothly. there doesn't seem to be any play in any wheel either.

my next thought is to swap to a different set of wheels/tires to make sure the noise is not coming from the wheels/tires.

does anyone have any ideas if i'm on the right track, or if there is anything else i should look into? any help is much appreciated.

How many miles are you at? Does it happen only when your accelerating, or all the time? Im at 120,000 and have had vibrations from everything under the sun, axles, bearings, hub, tires, you name it, Ive had to replace it. If its only under acceleration, it could be a bad axle, if its all the time it could be bad bearings.
as in, omg its oop, i.e. oh my god its out of print.

i have around 65,000 miles on it. no vibrations, just noise. as long as i am over 25mph i can hear it, even if i am rolling in neutral. it's easier to hear around 45mph, but still present around 65. haven't really gone over that since i've been hearing the noise.

i had the axle nut retorqued about 30,000 miles ago by billman. the noise started around 300 miles ago, so unless the bearings had already been damaged and slowly began to fail, the axle nut itself is not causing the problem. there is also none of the clunking noise associated with the axle nut.

Jack up the rear and see if there is movement in the wheel. Like this guy:

did that on all 4 wheels, but couldn't find any movement or play. is there always noticeable play when bearings fail? i'm suspecting it's the bearings, but i'm not completely sure.

You may be able to hear it just by spinning the wheels on jack stands. I had one the other day, I spun it by hand it was instantly obvious. One side quiet, other side noisy. Compare sides.

there was nothing noticeable. my friend and i both tried it. no obvious noise from all 4 wheels, and all 4 spun smoothly. the right side front and rear seemed to be slightly more resistant to turn than the left, but not difficult at all.

i'd like to eliminate one possibility at a time, but could it be something aside from the bearings that i should be looking at?

Does the sound change if you turn the wheel (like making a lane change)? Have you checked your brake pads?

yes, there is less noise when turning right, like on highway exits. i didn't notice a noise change when shifting lanes normally, but it's possible if i were to shift lanes aggressively.

brake pads looks like there is a lot of material, but i did not remove them to inspect.
the right rear rotor has a thin line gouged into it, like maybe a piece of sand got stuck in it. i heard a slight grinding noise last week, but was only there for a couple days. the gouge in the rotor goes around in a perfect circle though, so it still looks smooth. the pulsating noise may have come up soon after the grinding noise disappeared. not sure if it is or isn't related

I have the same "pulsating noise" issue, from what i gather the axle nut getting tqed to 240 seems to be the first step, most people have sucess with this? and do i need to call up a shop for the right tool to get it done?

if you have a torque wrench you should be fine.

I had the EXACT same issue a few months ago, Couldnt diagnose it. Drove on it(big mistake) it was a bad wheel bearing. it ended up braking the axle too. Just got it fixed this saturday, Parts where $114 for new axle and wheel bearing, $20 to get the new bearing pressed and $0 for labor since a buddy of mine helped me do everything. I also changed the rear break pads ($35) because when the axle broke it rubbed my disc till it was bright red. have the wheel bearings looked at to be safe. It should only cost a few bucks to get new ones pressed.

I believe mine was, if i turned left there was no noise and if i turned right there was a noise. My bad wheel bearing was on the left side. So if there was pressure on it it would make that noise. So I believe you should be able to determine which is bad by that method. good luck :tipwink:

how long did you drive on it before it gave out? was it just a pulsating noise, or did you have other symptoms?

not yet, but i plan to try this tomorrow morning. i will just swap left to right. if the noise moves to the other side, then i know for sure it is the wheels/tires. if it doesn't move, it just eliminates that possibility. i'm actually hoping it is this, but i highly doubt it.

even if the tires have no 'visible' damage, feel the edges with your hand, a cupped tired can make a lot of noise. I have the same kind of sound right now as well and went to torque the axle nuts to find they had already been replaced and were extremely tight. I had an 30 year experienced tech drive with me and hes convinced its tire noise. Im in the same boat, i dont want it to be too late and the wheel bearing take out the whole hub.

thanks for the tip. i'll keep that in mind when i swap wheels around tomorrow. were you able to confirm that was the cause for your noises yet?

it would be strange if the one tire was cupped though - air pressure is exactly the same on all 4 tires, and the rears are pretty much new. i've checked them every couple weeks since late november (just needed an excuse to test a new tire pressure gauge). but i won't rule this idea out just yet.

alignment specs can wear tires differently, but if yours are close to new/alignment correct it might not be the cause. Im also running about 3 degrees camber in the rear which is cupping the inside edge really bad. I haven't confirmed the noise, just took what I thought and my experienced tech friends input and made an educated assumption ( :o ) I might swap tires around and see if it goes away. Id also like to see what u come up with

my alignment looks good, also done within the last month. before and after were both even left to right. the only significant changes are rear camber went from about -2* (i can't remember exactly) to -2.2*, and toe in went to 1/16" or 1/8" total (i have the sheet at home).

hopefully i have enough time tomorrow morning to check this out, but i will report back with what i find.

I drove on it for about 3 months lol, It progressively got worse. I know I know, stupid me. So I was doing 60 on the highway and thats when the axle broke and it started wobbling really bad. I pulled off the highway as soon as I could and when I I looked, my rear left wheel was really canted and my brake disc was super bright red. Then next day my buddy pulled everything off and the wheel bearing was bad, axle broke at the nut. and yes it was just an intermittent grind, no other symptoms.

the noise i'm currently getting is not a grinding sound, just a rotating/pulsing/wobble noise (not exactly sure what to call it). i did have a slight grinding sound that went away, probably whatever scored my brake rotor, but that has disappeared for several days now. i will definitely be on the lookout in case a grinding noise returns.

It's like a squeak rather then a grind. Like when you bounce on a squeaky bed. Or if u've ever done it in a car, kinda like that.
