well went to the neighbor hood mechanic and had him put my 2004 mustang GT on rack to see what my popping noise in my front end was when I turn the wheel hard and he said it was bad rack bushing and wanted 160 plus parts to fix it. so I looked at a few threads on how to do install myself and 45mins or so later I had them out and changed. here is what they look like. my car again is a 2004 GT with 89k miles. I don't see these being bad enough to cause popping or vibration in the front to be honest. your opinions are appreciated.
