I had a similar noise in my 1997 Mustang GT. I took it to a Ford dealership and they replace the pinion bearing in the rear end. This was in 2007 and was charged $700. Now that repair would be much higher. I hope yours is less serious than this.
Normally a rusty rotor would not make a grinding noise. A grinding noise from the brakes usually indicated that the pads or shoes are worn down.
axle bearing or brakes or pinion bearing
your gears are grinding fu!
Front grinding could be a bad wheel bearing or in the front axle assembly.
it could be belt pulley rubbing on the timing belt cover or it could be the berries in the wheel but if its making grinding noise while ilding then def check your pulley make sure it isn't rubbing on anything or it could be the flywheel theres numbers of things to check over for the grinding noise
Could be, in need of brakes or wheel bearing failure,
They could, yes.
countershaft bearing could be problem
It could be a couple different things. Most obvious would be brakes. If a brake is sticking and worn you could be hearing a grinding noise as you accelerate. Second could be a driveline issue. Worn u-joints or something sticking in the transfercase (4X4) could also cause a grinding noise. Best advise is to find a reputable service shop and have them diagnose the noise properly. Good luck!
It could be the wheel barring hub.
i have a grinding noise on the front left wheel. i have taken the calipa off and i have one brake pad that is shot. could it be that or can it still be the bearing. how can i find out.
The expedition door lock relay could be stuck causing the grinding noise. Check to insure that the lock relay is working properly.
