Is the thrust washer that goes between the kuckle vacuum seal, and the diff outer tube seal still required? With the new tube seal design? Ford house does not show the thrust washer on their parts diagram. Says he don't know, but suspects that is the case.
this was the original location of the washer on my truck. i may be confused, but i think that is part of the old style tube seal? i dont think 2006 had the spicer 47766 thrust waher? i have read on other threads, where they were not factory installed on the 06?
Put the grooved one in first,then the hex one then the round one, then put the snap ring on
I don't think the 06 gets all that stuff, from what I have been reading. Just trying to make sure. None of that came off of it. Snap ring only on both sides came off.
Some guys remove that stuff and go with turning the hubs manually because they don't take the time to repair the vacuum seals correctly. That part allows the vacuum to reach the hub. If you read the manual, it applies a 30 second vacuum to lock the hub and a simular vacuum is applied to unlock it, something like 20 seconds. Very common for the inner hub seal to fail.
Easy test leave that part out. Install the snap ring and then the hub. Apply vacuum to the hose with a hand vacuum pump and with the wheel off the ground, give it a spin.... should lock in of it works correctly. If no vacuum makes it to the hub, no lock.
Or you just get out and spin it by hand. If that parts not there, vacuum never makes it to the hub... your getting muddy.
