What is the massive creak from the front of my car?

Any tips to what it could be or how much it would cost would be great. It is a Saturn VUE btw.What is the massive creak from the front of my car?Suspension rods need Replacement, they are worn out and dry of grease, but they are not serviceable, they need replacement.
