Ford F-150 Rear Driveshaft Assembly BL3V-4602-BD 3.5L 4WD

This is a complete rear driveshaft assembly for the 2011-2014 Ford F-150 with the 3.5L V6, automatic transmission, four-wheel drive, Crew Cab and the 145 inch wheelbase. It replaces Ford BL3V-4602-BD. The shaft is steel, measures 78.19 inches overall end to end, and has 31 splines with two teeth missing, which is the master spline that indexes the yoke. It comes with the U-joints installed.

F-150 driveshafts change with cab, bed length, wheelbase, engine and drivetrain, and a shaft that is off by an inch will bind or pull apart. Measure your old shaft end to end and confirm the 145 inch wheelbase before you order.

Replace the shaft when a U-joint is worn out, when the shaft is bent or dented, when a balance weight has come off, or when the slip splines are worn. Common signs are a vibration that comes in and gets worse with speed, a clunk when you shift into drive or reverse or get on and off the throttle, a squeak that follows vehicle speed, and a ring of rust dust around a U-joint cap.

To install it, mark the flange positions on the old shaft, support the shaft and unbolt it at both ends, then lower it out. Put the new shaft in, bolt up the flanges, and torque the bolts to the factory spec. Check the transfer case fluid level, then road test for vibration.
