I'm getting a whats sounds like standard tire roar, but it's not an even sound but more of a high - low roar. I thought the brake pad could be rubbing or have a high spot but when I apply the brakes the sound doesnt leave.

I hear it the most at 60 km/h or 37 mph, and becomes very faint anything above that. Below that it's frequency lengths.

I will need tires soon, but this has seemed to come over night or atleast I had the stereo off and noticed it.

Does this sound like tire wear (SO2) noise or perhaps a wheel bearing? only has 20,000 miles

 

Have you worn through some of the steel belts and they are showing? What about your tire pressures?

Still slightly off topic

I've made that "mistake" too, posting about the Bridgestone tires.
It's Bridgestone Potenza S-02.
Not SO-2.

On topic:
You could "feel-up" the tires to check for "saw tooth wear"
In one direction it feels smooth, in the other direction it feels like a saw.
If that is the case its tire wear.

No.. Tire pressure at 35 psi on all fours.. I check it monthly and it hasn't budged

I noticed the inside right rear tire has slightly more wear.

I hate my computer system because you never know when looking up a part if a 0 is a O and a I or l is a 1


Back on Topic:

I like my ride, but to "feel up" might be excessive, I'll do it but I will have Pamela Anderson in my thoughts when I do

Thanx for the info.

 

* Update *

Had the tires checked. No problem.

Still have the modulating whine. (only 30k on the car)


My next thought would be that the wheel bearing is starting to go. Prehaps tightening the axle nut will eliminate the noise.

Any other ideas?

 

The axle nut thing is usually a clicking sound as you take off. Left unattended, this could lead to a bad wheel bearing, which could give you a steady whine. Such a noise could also be a bad rear diff. Have you done anything to the rear diff? New gears? New fluid? Old fluid?

 

Owner before never changed it (got it at 20k)

Sooner after I changed the tranny/engine/diff which was about 8k ago (Amsoil full syn 80w90).

No other mods.

 

You put the same fluid in the tranny, engine and diff?
