I have a grind in the front end. I know these are vacuum released hubs. Only good info I can find is on f150s. Do these expeditions have a reservoir for the hub actuation? I replaced the vacuum actuator because it was me cracked, still need to get the check valve. Just curious if anyone has a diagram or tell me if there's a component I'm missing.

If you search "08 4x4 problem I think" in threads you will come across a recent thread where a member posted a good video from fordtechmakuloco with info pertaining to the hubs and grinding noises associated with them. Our systems are very similar to F150s

The actuators are exactly the same as on the F150. The Fordtechmakuloco videos are very good, check out these two videos.

I've seen the video, but thank you! I've read about vacuum reservoirs and 2 check valves. I cannot find that reservoir or the second check valve.
