If it is spring wrap, I guess I can live with it. When parking an automatic, I don't put any load on the parking pawl and I use parking brake. TSB 04-23-7 (Continued) 6. The driveshaft is subject to intense pressure and movement, and is required to strike a balance between strength (to bear the torque load) and inertia (caused by too much weight). But the clunking noise will always be noticeable whenever I start running, and always clunk at low speed. Some 2012-2014 Expedition and Navigator vehicles built on or before 5/13/2014 may exhibit a driveline clunk at highway speeds over 110 Km/h (70 MPH) during tip-out drive conditions. Re: Driveline Clunk: 2007 PreRunner Sounds like the infamous drive shaft slip yoke clunk. just a delay. It's only when rolling along at idle, then press/depress the gas. Because all of the components in the driveline have a certain amount of lash by design, changing driveline components may not result in a satisfactory lash reduction.
