Rotor hitting caliper mounting bracket.
Hey y'all, I just swapped out my rear wheel bearings (inner and outer) differential cover gasket and wheel seals. After I get it all put back together and take it for a drive I hear an intermittent LOUD squeaking noise from the rear end. I found out that the caliper mounting bracket is hitting the rotor. I torqued everything to specs and followed proper installation procedures. At this point I can't figure out what is causing it. Before I put the wheel on the hub will move freely in and out about a 1/4"-1/2". I've torqued the hub locking nut to specs and it's happening on both sides. Please help!!!

New rotors or are you reusing the old rotors? If they’re new, you might want to verify they are correct (match to the old ones). If you’re reusing the old ones, take it apart and try to find what you did wrong (rotor not seated fully?).

So what I'm reading is that the real problem is your rear wheel hubs are floating along the spindle? If so, something definitely isn't right.
Did you "seat" the bearings by snugging the nut while spinning the hub by hand?
If so I'm guessing you somehow were given the incorrect bearings because I read this all started after you R&R'd rear wheel bearings.

I torqued them down but did not spin the hub as I did so. I'll try that and let y'all know how I make out. It's definitely the hub floating in and out so maybe that's the problem. It does seem like it's not seating all the way.

Your wheel seal really shouldn't be able to stand up to the fine thread nut but just the same make sure it's seated on the spindle where it should be.
What year is this? Are you using a traditional wheel seal or a "Scotseal" that spins within itself?

Not sure what type it is but it does have a black plastic ring inside the metal seal. The seal is completely seated in the hub. It's an 02' f250 5.4L 4x4. It really just seems like it's not seating completely against the spindle.

They can be a tight fit on the spindle. You may need to tap the wb hub in place with a rubber mallet. I hope you haven't mangled the seal(s) thus far

I'm sure the hub is seated all the way and miraculously the seal is still in good condition. I cranked the hub locking nut past 60 lbs and it still has play. I'm starting to think maybe the hub itself is beyond repair.

Did the spindle appear damaged??
Something ain't right but not sure how the hub itself is "damaged beyond repair"?

I don't think there was the play in it that it has now. The bearings seemed to have been bad for a while now. I tore it apart to replace the wheel seals and when I put it back together it started hitting the caliper bracket.

I say maybe the hubs beyond repair because if the bearings have been bad long enough couldn't all that just wobbling around in there wear out the hub? It just doesn't make sense because I didn't have this problem before I took it apart.

Sounds more like the last bit of the original bearing may be still on the spindle. Causes the hub to be spaced outward by about a 1/4"....
Don't ask me how I learned that....
BTW, what exactly are you working on?
