I have a 99 firebird 3.8 that is making a high pitched squeal that seems to be coming from the drivers side front wheel. It only happens when i start the car cold and only when the wheel is moving whether braking or not. It only lasts about three minutes or so. My best guess was the wheel bearing needing replacement but im not sure if it is coming from the wheel or if it just sounds that way from the drivers seat. It doesnt happen when idling. Only during wheel movement. Thoughts??

Question type: Maintenance & Repair

Also when started cold its very fluttery

or irradic when idling. Ive replaced o2
sensor, egr valve, plugs, wires, air
filter, and done an oil change a few
months ago and the check engine
light is not on. This problem goes
away after idling for a minute or so.
Also ive noticed my gas mileage is
down considerably. I dont think this is
related to the wheel issue but im not
positive whats causing it
