I have a 98 Gs300 that just hit 160K and when i tun the wheel i get almost a metal scraping noise coming from the front right of the car. so i took it into a friend a Firestone so he could take a quick look at it and he said that the lower control arm was vibrating when you turned the wheel. So i don't know if i need to replace the lower control arm or maybe the ball joints. Has anyone had the same problem or any ideas of what it could be?

 

try ball joints and/or getting the bushings replaced

 

If he could not tell you then you need to go to a different shop and get a more experienced suspension tech to check it out.

 

I say do the ball joints asap and go from there.
