Got the first slick day today since I've had the 2001 4.4. Noticed that whenever I tried to stop the nose would always go to the right. Pretty scary. When we got home, I had my wife stand on the porch and watch the wheels as I tried to stop. Every wheel except for the rear left would be locked.

My DSC, ABS, and Brake lights have been yellow for a while. The speedo stopped working the other day but started again and has worked since then.
