I have this noise too. It sounds like it's coming from the front. I've checked all my wheels for any kind of play and everything felt solid.

I know this thread is old, but I want to see if anyone else has any updates to this.

Thanks!

Noises are particularly hard to diagnose. If you have checked all the obvious places and nothing was wrong, you will have to wait until something fails or you will be replacing all sorts of parts that don't need replacing. I always pay attention to the noises in my car as well and wonder about them, so i know how you feel. until someone with this specific noise has something go wrong, you're out of luck. sorry.

I don't have any mechanical skills but if it were me I would put the car in neutral while driving when the noise is going on and see if it goes away.
if it does it could just be some engine/drive train noise at that engine/drive train speed.....

another thing you could try is at a stand still rev the motor until you get to that rpm for the speed its making the sound and see if its there...just dont hold it for 10 min or anything.

another thing you could try is put the rear wheels in the air with the car on jackstands and get it up to the speed it makes the noise....

just some thoughts....
o and S2k Redhead I love the new plate

s2k redhead...

did you get a new s2k after this problem? looks like you did.

anyhow...question for you...

did the mechanic try resurfacing the rotor? i will be trying that this saturday. if it doesn't fix it, i will replace the rear wheel bearing.

it is definitely a rotational noise that occurs once per revolution of the wheel, so i suspect the rotor at this point.

Yep - unfortunately my problem was solved when some yahoo rear-ended me and totaled my MY02. The reason crash posted here is because he and krazik bought my MY02 and have been using it for parts for their race cars. I wondered if they had found anything that could account for the noise.

I replaced my rotors because I thought that might be the problem (and they needed to be replaced anyway) but that didn't fix it. I also thought it might be the differential, but that checked out okay, too.

I really thought it was a bearing but it never got worse - so who knows?

s2k red head...

well, now i want to see if my noise is the same as your noise.

my noise sounds like its coming from the rear, and i only hear it when braking at a slow speed (20-5 mph)...when accelerating from a stop up to about 20 mph, and turning right, but not when turning left.

the noise can be described as once per wheel revolution, and sounds like a creak or squeak...and maybe like there is a super-strong sticker stuck on the tire making a sticking noise being pulled off the ground when it comes into contact.

if this is the noise you have, please let me know...

i will be starting with the rotor...then the wheel bearing.

since you didn't change the rear wheel bearing, my guess at this point that your noise was the rear wheel bearing.

Hey guys, I have had some experience with the sound you are describing with other cars and current noise to some degree with my S. I attribute it to the half shafts. As these get some miles on them and especially with aggressive driving, they get sloppy and start making the rotational sound.

It can either be wheel bearing or more likely the input yoke going out in the diff or cv joint in the half shafts. To isolate any one of these as the problem you must hear it wile moving in gear as well as coasting in neutral. If it is tranny or clutch related usually you will not hear the noise when switching from coasting to driving in gear. Any more exagerated tone from the first three suspected wile turning to one side or another would also confirm one of these possibilities, not trans or clutch related.

If you have your car up in the air and rotate your half shafts in gear, you should have some movement front to back in rotation but none to very slight up and down, if you have exsesive movement up and down, there is your problem. Mine has been making a variant of this rotational noise from the back forever, so I am confirming the notion that Honda's play spec is looser then other cars, which has been brought up to me before. There is allot of play in Honda's drive train factory which is annoying and aids in creating more leverage to wear things out quicker.

To a degree this rotational sound is normal and I do have some up and down play myself, but has stayed about the same for a long time. I think at some point it will need some attention. I just learn to live with it but recognize it and pay attention to changes in sounds in my car. There is different severities of wear and you should be your own best judge of what stage of failure your car is in by paying attention to changes, certainly if more exagerated wile turning is a sign that your car needs attention now.

Hope this helps direct your attention to what could be going on. I prefer to educate myself so I can diagnose my own problems if possible. I find most mechanics today not very skilled in diognosis and will cost you ultimately after you pay with process of elimination, I hate that form of fixing problems as they are unecisary and expensive.

i resurfaced my rotor and the noise is still there...

next step is to change the wheel bearing and hopefully that fixes it.

Why don't you get under your car and inspect and jiggle things around? Its worth removing your cv boots and inspecting your joints. You may notice some metal dust which would be a clear indication of cv failure. If you jack up your car in a secure form and put your car in gear wile someone else is outside the car and viewing your rear wheels, if it is severe enough to make noise wile your in the car and driving, you will surely notice the wheel bearing as an issue in this form. With a worn out wheel bearing you will see the wheel vibrate and hop in the air as it is spinning in the air. A good wheel bearing will be smooth and show no sign of bouncing. Also check around the hub assem. to see if you can find any metal shavings or dust, other then break dust (Notice the location) Don't just waist money replacing things if you aren't sure they are the problem. There are ways you can find out what the problem is and prevent replacing parts that are still good, unless you have more money then I do, then go for it.

$10 to resurface the rotor is wasting money?

i appreciate your advice...but $10 as a possible and probable fix was not an issue for me.

secondly, my diagnosis in the car pretty much points to the wheel bearing...it occurs on right hand turns, and not left hand turns.

the rotor resurfacing was just a "lets up this easy fix does it" ...wasn't a big deal at all.

thirdly, the only other probably problem you suggest is the "cv" or a dirty hub assembly...both of which i doubt are the problems. there are many threads i've found through research that document this same problem and the solution was almost always the wheel bearing.

so just to let you know, i've done research and there are many cases with similar symptoms and wheel bearing being the solution.

i appreciate your input nonetheless.
