Higher mileage Raptors, it's time to start checking front hubs/bearings.

On these trucks the hub assembly interfaces with the Integrated Wheel End (IWE). It is critical that the IWE is compressed with vacuum during hub installation to avoid damage to either component. Once the axle shaft is inserted into the wheel bearing, the threaded end needs to be measured for depth within the wheel bearing. It it's too shallow, the splines are not aligned and damage will occur. If CV depth is correct, the axle nut then needs to be torqued to 30 lb.ft. That is of course much lower than a typical axle nut torque spec, which is often 150-300 lb.ft.
^ comment from FordTechOne concerning the wheel hubs. Seems like all of you haven't ran into issues yet, right? Thinking about doing mine soon.
Nope, not needed and seems to be more work than really needed. Fact is, the hub assembly will only insert all the way into the knuckle side if the gears groove together. It actually seems safer to me to do it that way than to have the inner gears retraced and then engaged only after the whole assembly is back together. Anyway, that is my thinking. I did not retract, had no issue getting the gears to mesh and all works perfectly. I did lube the living shit out of the gears though.
