steering/squeaking problem please help!

hi guys,

i bought a white gsr not so long ago and found out that it has some problems. i dont have much knowledge when it comes to fixing cars so id really appreciate all of the help i can get.

well, it started recently but everytime i turn the steering wheel more than 1/4th around, i get a noticable shake/rumble in the steering. also, at the same time, i would hear a loud sqeaking noice comming from all sides i think. do you guys think i need to replace something? bushings perhaps? or something with the suspension? my gsr is at 170k mileage.
