Hi,
I'm noticing a fine vibration in the steering wheel at 45 mph for the last few weeks. It doesn't always happen, but does about 90 percent of the time. The front tires are only about 3 months old, and have about 5,000 miles on them.
The car is a Chevy Caprice. The vibration is there under load, and also when coasting, in gear.
It's NOT a pulsing vibration, just a fine high frequency vibration, enough to notice.
Tires wearing in a certain way ? Wheel bearing ? U joint? Trans ? Power steering ?
Thanks
