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??
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
Does the car pull to one side while this is going on? Sounds like a brake issue. Perhaps a sticking caliper. That would also explain the poor gas mileage. If the brakes are dragging your engine will have to work harder to move the car. HTH. -Jim
Does the squeaking worsen any if you turn a certain direction? As far as the erratic idle, check for any vacuum leaks. Also, you can try cleaning your idle air control valve.
