When I hit 68 or 70 mph and above in my 1998 Chevy Venture, I can hear a creaking or squeaking noise that comes from under the hood, maybe a foot from the windshield, and directly in line with my steering wheel. This squeak/chirp/creak is intermittent and seems to increase in sound and frequency the longer I am at the 68 mph or above speed. When I slow down it disappears.
This is frustrating. I can drive all day at 65 mph and below and never hear the sound, but as soon as I hit 68 or seventy it begins. Any ideas?
Also, I have had the suspension inspected and no signs of any problem. As I said the sound is intermittent and as no rhythmic pattern or predictability other than speed.
Thank you,
