When I turn the steering wheel to left or right there is a grinding noise?

Answer 1

If you have put tires on your vehicle that are larger than the standard ones that came with your vehicle then the tires may be rubbing against the fenders. Look for wear on the edges of the tires and for rub marks in the fender wells. If it is not that, then I suggest you have a mechanic look at the car.

This noise could indicate low powersteering fluid,which can make a grinding or moaning noise when turning left or right so check fluid level,,also could be from a worn out powersteering pump not providing enough pressure...

*Also If the vehicle is front wheel drive and this noise occurs only when the vehicle is in motion then you may also need to check the right and left side CV joints on the drive shafts..many times the rubber boots covering these joints degrade and crack allowing dirt/moisture to enter the joint and allow the grease to exit,this will cause a grinding noise when turning..If left unchecked the joints will fail and the car becomes undrivable...

There are 2 CV joints on each drive shaft one right behind wheel housing(hub) and one next to the transmission...

CV= (constant velocity)

Over all it is best to have the noise checked out by a certified mechanic..
