Today, after about a forty minute drive on the freeway I arrived home only to have a huge clunking and grinding in the front axle when I tried to parallel park. I repacked the axles about four months back and the birfs looked good still. There was minor clicking, but that went away when I swapped the birfs side to side. This was my first thought of what could have possibly gone wrong. My other thought was that I also use 100 series pads up front and because they are not the perfect shape for the 80 there could be something wrong there. The truck isn't moving for awhile, but hopefully it can go by friday. I have a date that I don't want to miss.
