HELP! vibrating sound when turning at certain angle

[freelancer]

i got a 95 240sx. when the car is turning right at a certain angle the front right makes a vibrating sound, its louder when im on high speed, but once pass that angle the sound goes away. i dont know how exactly to describe thaat sound, but virbrating is probably the closest sound, also i can feel my steering wheel is virbrating very slightly.

thank you for you help
