I have a grinding noise that seems to be coming from the rear of the car when I put full lock on either direction it sounds like a wheel bearing but this is not the case has anyone got any advice as to what this could be please

 

welcome to the forum. Worn Brakes,

 

You might check your emergency brake to make sure it's not hung up.there is a cable under the car that goes to the rear brakes, reach under and pull the cable to see if there is any slack.
