Chevrolet: 2002 Chevy Venture - Noise Above 35 MPH, cv joints, chevy venture

Question
QUESTION: My 2002 Chevy Venture starts making a noise that almost sound like a "loud motorcycle" under the hood (front end) starting about 35 MPH and gets slightly louder up to about 55 MPH. At first I thought it was the engine or transmission - but I put the car in neutral, at the same speed, and the noise continues. My tires and brakes seem OK. No leaks from the CV joints or transaxle. Any suggestions? Thanks!
ANSWER: Hi
how is the exhaust system or the ex.sensor. or a crak in the ex. system

QUESTION: Exhaust is fine. I took it to the dealer. It was a bad front wheel bearing. I've never heard this type of noise with a bad bearing - but its fixed now and now I know... Thanks anyway!

Answer
yes sounds can and will travel; I had a woman come into my place at 7:00 in the morn and she said her car was making a sound like a police car, so I was tried not to laugh, well I open the hood and her cat wad on the water pump to keep warm and the fan when she started it up snapped bottle cats front feet. she wanted me to get out I said hell no so my boss came and told me to go home and get a gun. well I did and I told her the cat was suffering and the best thing was for me to shoot it,  so I did. so noises can come from any place.
