About a month ago I bought my first Expedition. It's. 22 Limited. The ride is a little rough. Now the dealership to certify it put on some super cheap tires. So I'm thinking the ride will smooth when I put the correct rated tire on. They put a much higher speed rating on so it's a harder compound. Does anybody know if you can add the CCD? When I go to the Ford parts website to look at replacing shocks the only option that comes up for my VIN number is CCD in the front, but I have looked and the shocks don't look anything like the ones on the website. So it makes me wonder if they've replaced the shocks but didn't put those on to save money. I would think if you didn't replace them when it had it before you'd throw a code.
