FORD: LINCOLN: 2002-2005 Crown Victoria, Mustang, Explorer 2002-2005 Town Car 2003-2005 Expedition 2003-2005 Navigator 2004-2005 F-150 MERCURY: 2002-2005 Grand Marquis, Mountaineer This article supersedes TSB 04-17-5 to update the model year and vehicle line coverage. ISSUE Some 2003-2005 Expedition/Navigator, 2004-2005 F-150 vehicles equipped with a 9.75? or 8.8? limited slip rear axle, and 2002-2005 Explorer 4dr, Mountaineer, Crown Victoria, Grand Marquis, Town Car, and Mustang vehicles equipped with 8.8? limited slip rear axle, may exhibit a chatter, shudder, a binding sensation, or a vibration during low speed turns. On 4×4 vehicles, the sensation may appear to be originating from the front axle or the steering gear. ACTION First verify the condition. On 4×4 trucks ensure that the vehicle is in 2WD, to isolate the rear axle. On all vehicles, turn the wheel fully right (or fully left) and then accelerate the vehicle. If the condition is verified to be in the rear axle, replace the limited slip clutch pack. SERVICE PROCEDURE
