I'm new to the group. I have a problem with my Mustang. It's 2006 v.6

When I take speed and I get a curve, I feel that the car is jumping from the back and like it's getting in. In the same way, I had a lot of splendour with the front suspension because I was knocking. I don't want to guess and spend on something that isn't.

I have been told what the stabilizer screws and the stabilizer bar bushings or the lower control arms can be.. will it be?
