You'll need a replacement steering wheel with the volume and seek controls on it. This is also a good time to get a leather wrapped steering wheel, I did that with mine. You can pull a steering wheel from your local junkyard, or buy one off ebay, just be sure it fits your vehicle. My wheel came off a 2018 Ford Flex SEL, the electrical connection is the same.
Tools needed:
Allen wrench or long screwdriver to remove airbag
T50 Torques bit with extension
10mm wrench to disconnect battery.
Turn your vehicle on, make sure your wheels are straight, it'll make your life a lot easier putting the steering wheel back on.
Turn the vehicle off once wheels are straightened, disconnect negative terminal on the battery, let the car sit for about 20 minutes to let residual energy drain from the capacitors, airbags can still deploy if the capacitors are still charged.
After 20 minutes,
Remove airbag from old steering wheel. Once removed, place the airbag on the passenger seat FACING UP, the Ford emblem should be facing up, the airbag will become a projectile if it's facing down and it goes off for any reason.
Remove steering wheel. You can alternatively replace just the switches on your existing wheel, but that would require further disassembly. Be sure to not mess with the clockspring, place a piece of tape to keep the clock spring from spinning (Spinning it and putting the wheel on it will destroy it and may cause the steering wheel controls or horn to not work in any position and it'll turn the airbag light on).
Disconnect the electrical connection at the clock spring and remove the bolt holding the steering wheel on. Wiggle the steering wheel slowly and slowly remove it from the steering column. You may also notice the wheel moves while trying to remove the bolt. You can jam your legs against the steering wheel so it doesn't move as much.
(Installation is reverse of removal)
Once your old wheel is removed, feed the airbag connectors through the new steering wheel, and line the steering wheel up with the electrical connection on the clock spring. The steering wheel should go on in the same position (ideally center position) as it was removed.
Once lined up, tighten down the bolt and reconnect the electrical connection to the clock spring.
You can use your old airbag with the new steering wheel. Reconnect airbag connections and put the airbag back in. It's just clips, line it up and press firmly in, you should hear it click into place.
When you're finished, reconnect negative battery terminal and change these in FORScan:
IPC (AS BUILT) 720-01-02 to xxx0 xxxx xxxx
and
SCCM (AS BUILT) 724-03-01 to xx01 xxxx xx (if you have SYNC)
Also to note: If your PIU steering wheel has the media/mute buttons and not the voice and redial buttons, those buttons on the new steering wheel will not work as you don't have a SYNC module.
You will also have 2 permanent DTCs set for the GFM when switching the wheels. You can clear it by unplugging the GFM module. You can just ignore it entirely as it won't set a malfunction indicator lamp on the dash.
Hope this helps, good luck. This was the end result of mine.
