Grinding Front Driver's Side Wheel

Sup Runner brahs,
I've searched the interwebs low and high for an answer to this problem, to no avail. Several people had similar issues that, from what I can tell, differ from mine. :sad:

About 2 weeks ago, my '99 4Runner Ltd (4x4) started emitting a squeaking noise from what I believe to be the front driver's side wheel area. It sounded similar to a worn brake pad, except that it went away when braking, instead of making the noise when I hit the brakes.

I ignored it and it went away.:art:

Fast forward to yesterday; the noise came back with a vengeance. It's much louder and more worrisome, so the ol' ignore it and hope it goes away won't fly this time. It's now more of a grinding noise, which will lessen if I gently tap the brakes, and it gives me a shudder on the brake pedal towards the end of the braking - similar to an ABS, but definitely not the same.

From a cold start, there's no noticeable noise. After a bit of highway driving, it starts creeping up.

For background, I lifted the car about 3 months ago. ToyTec BOSS, with 3" of lift in front and rear. Installed new LBJ's, inner + outer tie rods about a year ago. I'm attaching an mp3 of the noise. It starts with me driving and then I hit the brakes around the 10 second mark.

Any thoughts, ideas? I'm thinking maybe a seized caliper but don't have much experience other than what I've picked up here and there.

Thanks guys.

Sounds like a brake issue to me but its hard to tell from the audio clip. It's not really a grinding noise but more of a "wear sensor on the brakes" kind of noise.
 
If it's a bad grinding noise it's likely a wheel bearing.

Jack the side in question in the air so the tire is off the ground. Grab the top and bottom of the tire firmly, and try to rock it back and forth. If there is ANY play, your wheel bearing is shot.

Poke something through the wheel (like socket extension) and use a little force to bend the dust shield away from the wheel. You could have a rock lodged in there, or something could have caused it to bend towards the rotor. Go all the way around, not just one spot.
