topichka Posted October 6, 2006 Share Posted October 6, 2006 Hello, I have an 01 GS430 with 123K miles. I've had this very subtle humming noise that comes from the right rear of my car. I thought it was my tires but I had them replaced this last weekend and the noise is sitll there. It's not that loud, but increases in volumne slightly between 40-50 miles per hour. It's most noticeable when I'm in a sweeping left hand turn, around 40 mph. It doesnt' seem to make the noise when I turn right. I thought it might be my wheel bearings but the guy at the tire shop said he put it up on the rack, turned the wheel by hand and couldn't replicate the noise. Then I thought it might be the rear diff. so I took the car out, drove until I could hear the noise and shifted into N, but the noise didn't change at all. The car is out of alignment--I can't feel it but when I took my old tires off, the front right tire was basically bald in the outer edge. Could this be an alignment issue? I'm not the most mech. inclined so any help will be greatly appreciated. Thanks, Brian Quote Link to comment Share on other sites More sharing options...
