ISSUE
Some 2010 Taurus, Edge, Flex, Fusion, Milan, MKS, MKT, MKX and MKZ vehicles built 10/1/2009 to 12/31/2009 and equipped with all wheel drive (AWD) may exhibit a shudder/chatter/vibration driveline sensation during a tight turn, or a thump/clunk noise on light acceleration. These symptoms may also occur under 40 MPH (64 Km/h), on tip-in, driving uphill, or towing under heavy acceleration.

ACTION
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

1. With the vehicle on a hoist, check the power transfer unit (PTU) by using one or both of the following procedures:

a. Transmission in Park - driveshafi can be rotated by hand or using a strap wrench.

b. Park brake set, engine running at idle, transmission in drive, foot off brake - front wheels turn and driveshaft does not.

2. If one or both of these conditions are present, replace the PTU. Refer to Workshop Manual, Section 308-07.
