2001 Chevrolet warner bros Venture van
6 cylinder

tech = jk
question = makes noise when driving on road when going around curves
its quiet. If you turn the wheel loose it goes straight if you turn just
a little either way the noise stops.





JK:
The noise you are describing could be tire noise or possibly a noise front hub
bearing.  Hub bearings will make noise when turning in one direction, and not
the other. That is,  unless both are noisy.
To check for a tire noise, rotate the front tires to the rear and see if the noise
goes  away or changes.
For a noisy wheel bearing, drive the van straight. Turn the wheel slightly to the
right. If  the noise is there, or gets louder, then the left front hub bearing is the
most likely cause.  This is because the body roll puts the vehicle weight on the
lf. side during a right turn.   Same rule applies for a left turn.

Anti-lock brakes are designed to prevent skidding and help drivers  maintain steering
control during an emergency stopping situation. In cars  equipped with conventional
brakes, the driver pumps the brakes, whereas  in cars equipped with four-wheel ABS,
the driver keeps a firm foot on the  brake allowing the system to rapidly and
automatically pump the brakes.  Because the wheels don't lock up, drivers have the
ability to steer around  hazards if they are unable to stop in time.
