only thing i know that will make brkes grind, is worn out brakes
maybe have em checked at a different mechanic
If you suspect something, get them checked. If you get vibration while applying the brakes, get them checked. If you get grinding noise from the brakes, get them checked.
your brake pads have worn out, so i would get some new ones if i were you.
have the back brakes checked sometimes they can sound like the front
It might be the clutch but get it checked out
What activities are checked as always
Probably a problem with the transmission "valve body". Have it checked out with a transmission specialist.
broken motor mount(s)
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.
Check or have them checked immediatley. They are going to fail REAL soon.
Have your brakes checked, rust or wear on brakes can cause grinding when turning.
Most probably the driveshaft(s) or the axles are worn. Get them checked.
Have it checked for codes. The code should give an indication to the cause.
