I bought a 2001 mercury cougar last week and the seller said the drivers side rear strut needs to be replaced. When I hit bumps, I can hear that something isn't right back there so I guess she was right. I plan to bring the car in for an oil change asap, but I don't wanna call until I know if they will need to replace the strut as well or not. My dad has been obsessed with cars and has been doing his own work on all of his cars ever since he could drive so he wants to look at it and see if this is something he can do himself to save us a little money. Neither one of us have dealt with this before so I need to know what I have to do in order to check this out and complete it myself.
