About a month ago I changed the pinion seal on my 2006 GT. All went well until I started looking around on the internet and got into this "crush sleeve". I am almost positive that I overloaded the bearing and now there is a noise coming from the rear end but, only when I turn though. I'm thinking that it is the bearing making the noise but not for sure. Also, if it happens to be this "crush sleeve" how difficult would it be to change?
