Road noise?

Hey all,

Last weekend I went camping up a dirt road, and I took my '99 OBS. Well, it was about 15 miles up a dirt road (mostly smooth, occasionally some gravel/ruts/bumps, etc), so needless to say, I didn't drive slow the whole way there and back (nothing more than 30 or 40 mph). However, now I seem to have a lot of "road noise" coming from the rear end while driving at any speed >30mph or so. I had my tires balanced and rotated after I got back from camping, which didn't seem to improve things at all.

I'm not sure where the noise is coming from specifically, but it does sound like it's coming from the rear. It's not a grinding noise, or anything that bad, just more like a low rumble...it honestly just sounds like my tires are REALLY loud, causing a lot of reverberation through the back of the OBS.

Anyone have any ideas?

Thanks!
Matt

Does it sound like mud tire noise or does the noise go up with speed.You may have a wheel bearing going out.

Mud tire noise? Do you mean the sound that mud tires make, or a sound caused by mud in my tires? I'm not sure what sound having mud in my tires would make, so I'll narrow that one out. However, now that you mention it, yeah, it might sound like the sound of mud tires (but a little deeper pitch, maybe?).

Wheel bearings...that doesn't sound good.

That sounds a bit fast for a bearing failure, is there any chance you have one or more small stones lodged somewhere in the brakes? Does it sound like a scraping at all?

Also, just on a wild guess, is there any chance there's something wrapped around the driveshaft?

Nope, definitely doesn't sound like a scraping noise. It's more of a low rumble.

So, does it vary with speed? Or road texture?

It gets louder with speed, but not sure that it's really much worse at say, 60mph than it is at 40mph, etc. I don't think road texture seems to affect it at all.

OK this is probably a dumb question, but have you checked you tires for small stones lodged in the treads? I've noticed quite a lot higher road noise from the tires right after going off road, hundreds of small (1/16 to 1/8 inch) stones lodge in the tread pattern. It seems to go away after some distance driving just on road..

Yup, already checked for that. Actually, when it first started happening, it's because my rear wheels were caked with about 1/16" of dust all the way around the inside of the wheel. I was hoping that was the cause of it all, but ...nope!

I would think that a failed bearing's sound would vary directly with speed. I asked about road texture thinking it might be some broken bushing that would transmit a rumble, but if that were the case you should be able to get different sounds out of it by driving on different surfaces.

Any chance you could have someone else drive it while you sit in back and try to isolate the source?
