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.

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.

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.

well, it's definitely not the tires. tried swapping left and right and the noise did not move. then just to really be sure i tried a different set of wheels, and the noise is still there.
tried spinning the wheels while i had it up again, but there is no obvious noise difference between all 4 wheels.
most likely bearings on the right, but still can't determine if it's front or rear. my ears might just not be trained well enough.
so, anyone know a good mechanic around maryland that stocks parts to repair this? all dealerships around here seem to special order anything related to the s2000 (even the brake bleeder dust caps), so i'm trying to avoid them.

your local Napa or Autozone should carry wheel bearings and some have their own machine shop to press. Napa charged me $20 to have one pressed. My buddy works at napa and got me both the axle and the wheel bearing for $114 no taxes. I think normally it would be about $150 for both. The wheel bearing I think was about $25. Im sure you can get one for around $30-35 and have it pressed for the $20, so you're looking about about a $50 fix, Assuming you do the removal and reassembly of the parts yourself.

the bearings would need to be replaced, but how likely is it that the hub is damaged and needs replacement? i know the issue is on the right, and i'm thinking more and more that it's the rear, but i'd rather not buy both front and rear hubs to throw at the car to fix it.
new question: if it is the right rear bearings giving out, do i need to be worried about the left rear bearings? the reason i ask this is, would the damage be from not tightening the axle nut early enough, or can it be considered as normal wear? (there are over 65,000 miles on the car by now, axle nut tightened around 30,000)

Yes, I only had to replace the axle because it broke close to the nut. If you have a broken axle you would definitely know. As of now I would think it's just your bearing.
As long as you tightened the nut before it had any effect on the bearing you should be ok, they are independent from each other so one wouldn't affect the other.
I never tightened any of the nuts before, I have owned the car since 6k miles, so I doubt the previous owner did either. Did you tighten all the nuts at 30k miles? I would say normal wear and tear if it was only the one.
For what it's worth I had 100k miles on mine when I got the symptoms. You will have to see what damage there is when u pull the hub. If the bearing damaged it to the point that the new bearing isn't sitting tight, you may need a new hub. When I got my new one pressed it fit in well but any less I would have needed to get a new hub too. I may get a new hub in the spring just to be on the safe side.

noise seems to be getting slightly louder, but still not grinding. had another friend more familiar with the extra noise of driving a roadster ride along, and he said it was definitely the right rear. time to buy some parts.
