My SVT has 54,6xx miles, and I'm running BFGoodrich T/A KDW's, which have a reputation for creating a lot of road noise - the tires are probably not quite halfway through their tread life.
Anyway, driving the car has become almost unbearably loud, especially between 60 and 65 mph - loud enough that it's difficult to have a conversation in the cabin. The noise drops off fairly substantially once you get above about 68 mph or so, but is still quite noticeable.
What makes me think that it's a wheel bearing is that the noise is most pronounced when I either have the steering wheel perfectly straight, or when I am going around a sweeping left-hand curve. When I go around a sweeping right-hand curve, the noise virtually disappears.
The easiest thing, I suppose, would be to swap the KDW's off for my snow tires (BFGoodrich Winter Slaloms) and see if the noise goes away. Before I do that, however, is there any way to diagnose a wheel bearing problem before I take it back to the dealer?
I bought an extended warranty out to 75,000 miles, and I am pretty confident that a wheel bearing replacement would be covered. I just want to know if there is any way for me to confirm it for myself before I get the dealer involved.
Many thanks in advance.
