when i turn right it makes a grinding noise. when i hit the brake sometimes it grinds. i inspected it and it all looks good. i drive a 1989 nissan 300zx. maybe some1 in this field will no.

could be brakes or a couple other things but grinding usually says wheel bearings

Maybe its a ball joint or your brake pads or discs need changed.

If you have big wheels it could be affecting your suspension - take it to a garage to get it checked out. If you listen for worse road noise and a bit of a hum i would say you just need the ball joint replaced.

Best bets are the brakes or the wheel bearings. The noise when braking suggests that the brake pads are worn down to the metal and need immediate replacement.
