Ford Tech Tip: Clunk or Bump When Starting from a Stop

Some 1997-2006 Ford E-Series, 1999-2006 F-Super Duty, 1997-2003 F-150 and 2004 F-150 Heritage 4x2 vehicles may exhibit a driveline clunk or bump that occurs as the vehicle starts to move forward following a stop. This condition may be caused by the slip yoke not sliding smoothly on the output shaft splines.

How can a mysterious case of tire wear occur in a perfectly aligned vehicle? It happens and the answers aren’t always simple. To better explain, let’s go back a few decades when I aligned a 1983 Mitsubishi RWD pickup, only to have it return a month later with a tire scuffing complaint.
