Sounds like the Shop you went to gave you an incorrect diagnosis.
I mentioned to you what to do via a PM.
Before you replace anything further, follow my two suggestions in the PM.
One area to check would be the tension arm, where it passes thru the lower control arm.
Here's what my PM suggested;
I would suggest you do one of two things;
1. Remove the wheel from that side of the car, and rest the frame on a jack stand.
Take a pry bar, and try to exert force on the various suspension components, as if you were trying to force the ball out of the socket (for example). You should be able to detect movement IF that joint is worn.
2. Take the car to a different shop and get a second opinion. If the two opinions match, then your all set.
Let me know how you make out.
