My front left tire was worn down to the threads on the outer corner (not the alignment), and now I'm hearing like a whirling/humming/grinding noise when im below 10mph and stopping or turning right. I JUST put a new tire on because I don't feel like having a blow out and killing myself. While it was on the lift it was checked out and the right wheel outer tie-rod had alot of slack in it. I'm changing that asap. But the grinding/humming noise would be the front wheel bearings correct? It made the same noise when my bro's truck's front bearings were shot. I'm putting on new control arms with new balljoints and control arm bushings(hoping to fix the left wheel wear) and new slotted rotors with new pads, bearings, and seals. How do I adjust the wheel bearings?

Spin the wheel and tighten the nut tight to seat the bearings and then let off how many turns? How does everybody do it?
 
From the Ford Mustang Service Manual:

1. Raise vehicle until tires clear the floor.

2. Remove wheel cover. Remove grease cap from hub.

3. Wipe excess grease from the end of the spindle. Remove the cotter pin and nut retainer. Discard the cotter pin.

4. Loosen adjusting nut three turns. Rock wheel, hub, and rotor assembly in and out several times to push the brake shoe and linings away from the rotor.

5. While rotating the wheel, hub, and rotor assembly in a counterclockwise direction, tighten the adjusting nut to 17 - 25 ft-lb to seat the bearings.

6. Loosen the adjusting nut one-half turn, then retighten to 10 -28 in-lb, using an in-lb torque wrench.

7. Place the nut retainer on the adjusting nut, so the castellations on the retainer are in-line with the cotter pin hole in the spindle.

8. Install a new cotter pin, and bend the ends around the castellation flange of the nut retainer.

9. Check front wheel rotation. If the wheel rotates properly, install the grease cap and wheelcover. If rotation is noisy and rough, follow procedures under "Replacement and Lubrication.

10. Before driving the vehicle, pump the brake pedal several times to restore normal brake pedal travel.
 
Replace those bearings ASAP. I have seen customer come in with old sample parts. The bearing got so hot it seized to the spindle. They need spindles, rotors and bearings..because they waited too long to just replace bearings.
 
I always tighten the nut. Then you use a flat screwdriver between the
housing and the big washer. Keep loostening till you are able to slide the
washer under the nut. Go to next looser hole for pin. Check by spinning wheel and
seeing if you get any wobble
 
I have been using the Ford Service Manual procedure posted above for 25 years or more, or a country boy variation, on my Capri, Mustangs, and trucks.

Pack with grease, install, tighten the nut while rotating until it gets a bit hard to turn, loosen, until it spins freely, hand tighten, then back off about 1/8 to 1/4 turn, and insert the cotter pin.

Seems to work fine.
 
So I didn't have time to order the parts because shipping would take too long. I needed to change them ASAP. So I go to the parts store and when he asked me which brand of bearings do I want, I replied, "are any of them made in America or are all of them made in China?" He came back after looking at them in the back, and told me all of them are made in China. So at that point I just bought the cheapest one since they are all the same piece of crap. It's a sad day when you can no longer buy US made parts even if you want to pay at the extra money.
