MOTOALL Auto Locking Front Hub Axle Actuator for Ford Expedition Lincoln Navigator 4-Wheel Drive 4x4 4WD Replaces 7L1Z3C247A 7L1Z-3C247-A

You get what you pay for. Ordered 2. One has a slight vacuum leak out of the box. Didn't think to test before install, so it's on me, but the bypass is negligible with the engine running under no load.

Easy to install

Great product and price will beat any any auto store

Perfect fit! Easy install, restored 4 wheel drive to my pickup!

I just installed this on my 2012 f150 a couple days ago and so far so good.
