Mechanical Question

My mom's car is making a "womp womp" when you turn the car left and right. She thinks I know what is wrong so she took my car and now I am stuck with her car (92 corolla DX). Anyyways does anyone have any clue to what is wrong. I went to a mechanic and they want to ripout my CV Boots so they could look at it. I said no because those are fairly new boots (4-years old) and if they could not find anything wrong I would still have to buy new boots cause they will destroy the one the want to take out of the car. Does anyone have any idea what is making the womp sound when you turn left or right?
