It is not safe to drive. Possibilities for cause, maybe wheel bearings, brake pads worn down to steel backing plates, if its front wheel drive there are even more possibilities. It has to be repaired before further driving.
If its front wheel drive possibly an axle.
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.
sounds like you need pads cheap fix
Best to get merchanical attention very soon. Never a good idea to drive a car making silly noises.
New CV joints will fix the grinding noise
The pump will need replaced if it is grinding.
The rear of a Ford Explorer may have a grinding noise when driving, because the muffler may have came loose. The u joint may also be loose and cause a grinding noise.
I have the same problem if it was making a grinding noise contact ego-fly if its not making a grinding noise the rotors might be hitting each other
It could be a number of things. It could be the drive plate spindal hitting something every time it spins...
a. controller failure b. the read/ write head is in contact with the platter c. hard drive is in power save d. hard drive is in labor
engine problems not trans.
Sounds like you need a water pump, The bearings in the water pump are making the noise not the pulley.
