First, be aware that this could be a very dangerous situation. While it is impossible to diagnose the problem from such little information, there is a fair chance that you have a faulty wheel bearing. Please have a mechanic check your car right away.
why does my 1996 ford tarus wagon make noise when i turn key in ignition
wheel hub
Could be a wheel bearing/hub going bad.
Most likely the C.V. joint needs replacing. The grinding noise is usually a sort of clicking sensation. Another problem you might have is similar the the problem i had with my clio. when i put the steering on full lock i could hear a grinding noise. the thing i did was have my car checked by a garage and they found that the suspension had shattered. you need to get it checked.
that's called a turn signal
Drive the car on the road about 25 mph. Weave the car left and right. If the noise changes then it is the front wheel bearings.
If a car is making a grinding noise in the right back wheel, it could be a sign that a wheel bearing is failing. It is necessary to take the car to a qualified mechanic for repair.
sounds like a wheel bearing.
A broken car =]
If the "grinding noise" is present while cornering left and all but disappears when cornering right, my experience* says it's your right rear wheel bearings needing replaced. * My '96 did the exact same thing another thing to check is my exhaust pipe would rub the rear suspension on the passengers side and make an awful noise only when turning left and it would be worse with more weight in the car
your brake pads are probley wore out so its grinding on your rotor
sounds like the starter is "grinding" on the flywheel teeth. Could just need a shim or two. Or the starter teeth may be getting worn.
