I own a 2005 g6. When I turn I hear a thunking
noise in front when I turn a corner. My mechanic says I need all new front suspension. Any ideas or suggestions thank you so much!

It may be just the CV Joints have worn to the point where they thunking when turning - and have a load on them. I don't know how many miles your car has on it or how you drive it. Saying you need new suspension is a rediculous Blanket statment, while that may also be true, it is very vague. I wouldn't take your car there for repair!!!
