Just bought a 2000 Excursion. It has what looks to me as about a 3" lift. I threw new tires at a front end vibration. There is less of a vibration, but still present. Bought hub assemblies. Previous owner installed superwinch hub locks. During tear down, I found that the thrust washers were installed behind the hub assembly. Upon re-assymbley and putting washers in factory location, I have to significantly pry the axle out to reinstall the lock ring. Seems like possibly too much drag, nevertheless I reinstalled the hub locks. The locks, in the free position, immediately engaged the axle and won't release, and definitely more drag than desired. Any thoughts?

You could be having several issues that may not even be related to the hubs.
A little more info on the symptoms would help.
A first suggestion would be to pull out the old hubs and buy new Warn or Mile Marker hubs and install according to the directions provided. That might not cure your vibration but it will certainly clear up any issues with the hubs. Re-using old, improperly installed hubs sounds like a recipe for future problems.
May want to reconsider your thread title. Not sure what any of this has to do with the Differential.
Hopefully some others will chime in with more advice.
Also, check out the tech folders for information about slop, wander, vibration issues. Plenty of reading and may help get you started down the proper path to correct.

The hubs assemblies are new, the hub locks are existing aftermarket. My biggest concern right now is why the axle is so tight in the new hub assembly with all the thrust washers installed in the original direction and order, and hub locks engaging.

Have you gone through to make sure the old vacuum assembly has been properly disengaged? You could still be getting a vacuum pull on the hubs.
Also. I'm sure you did, but was everything properly cleaned and greased during re-install.
There's just not a whole lot to go wrong with manual locking hubs unless the esof system wasn't disengaged at the hubs. The switch should only be engaging the transfer case at this point.
Really good info on page two about halfway down. I'd check that out and see if it rings any bells. https://www.ford-trucks.com/forums/1...excursion.html

The factory wheel bearing assembly has several thrust washers.
One that goes between the seal on the axle shaft and the wheel hub assembly. This one needs to face a certain direction as it is not flat.
then three washers go in the wheel bearing assembly behind the lockout hub.
ventures truck parts has a couple videos on YouTube that show the proper orientation and location of the thrust washers
