Which part of the brake assembly was loose? The line into the hub area? Or the entire rotor/caliper?

Check the dust shield by the rotor, I've seen them get bent and rub. A little movement in the caliper is normal.

The caliper was somewhat loose. When I say loose I mean I could budge it like 1/8" or so when grabbing it. The rotor was solid.

Any chance you could explain where this is? I'm new to this whole do it yourself movement when it comes to vehicles, but I'm tired of paying other people to do what I am capable of. Thanks.

It literally is the shield that sits between your rotor and wheel. Its a thin sheet of rounded metal the mount onto the wheel bolts. Just google "brake rotor dust shield" and you'll know.

And I don't believe thats my problem. My dust shields are pretty straight and I think after 5 months of rubbing, it would eventually shave it off enough to where it wouldn't be making contact

Gotcha. I see where it is now. Is that easy to see under the vehicle without disassembling the brake assembly? Only pictures I saw were of everything taken apart.

You'll be able to physically see the shield without disassembly, but I would just take the time to get that tire off and check the condition of it. I'm gonna do the same.

Disc brake squeek is fairly common.
I agree there is no way that it is a U joint. At 10 - 35 mph you would be hard pressed to discern a single rotation of the driveshaft.

BUT
You should check the wheel bearings. They rotate at the same frequency as the wheels and might have metal to metal rubbing. I ignored a squeek on my '69 mustang until one day when my right rear wheel and axle passed me on an entrance ramp The ford rear held the axles in with pressed on bearings and one finally let go on a long turn.

Definitely don't want that! I'll have to get some new ones for my 8.8.

My issue is not a disc brake squeak. Brake squeak is constant while applying the same amount of pressure to the brake. My issue sounds more of a creak (image a creepy old door opening creak) and is only heard when applying medium-light pressure to the brake pedal while in the 10-45mph range. When I'm going faster, I don't think it makes the sound. That or I just can't hear it. Could my issue be something bearing related even though it is not a constant sound?

So you only hear it when you lightly apply the bakes and no other time? like maybe speed bumps.
If it is suspension/bushing noise you would hear it anytime the suspension moves a little like when you apply the brakes. That would sound like a creaky door and if your brakes are a little warped it would be cyclic as the brakes grabbed more and less.

Can you isolate front to rear? left to right? Real tough to solve with a little info.

I've isolated it to the drivers side rear wheel. Only happens when applying 30-40% brake going 10-45mph. Doesn't matter the road...smooth, rough, uphill, downhill, dry, wet, etc... Yesterday I was trying to find a parking spot at a mall and every time I'd brake you'd hear it...creak...creak...creak...creak...

Judging by the new info my best bet would be your rear brake needs work. It is probaby adjusted a bit looser than the passenger side and has some rust/binding on the springs.
Here's why I think that way'
When you apply the brakes lightly the fluid flows through a single line back to both rears. The proportioning valve sends more pressure to the front until you press hard enough to balance out the pressure. With the shoes only lightly contacting the drum there is still room to shift a little. If there is rust on the springs and contact points every time there is movement there will be noise.

Pull the wheel and do a visual on the brakes. with the drums off push the pads back and forth a little to see if you haer any creaking. Get some brake cleaner spray and doush down the whole assembly. If the shoes are still in good shape, the springs are all in place and resonably good and the drums are ok put everything back and see if it still creaks.
