Rotational Grinding

I have a 1995 4Runner 4WD SR5 that has a 3" rough country lift/suspension, 2" spacers, and 35" MT Tires. I just recently got a new Jasper motor, ujoints, front wheradiator, starter, flywheel, and alternator.

As l'm picking up speed to about 50 mph and naturally let go of the gas pedal, there is a rotational grinding noise coming from the front end. The noise doesn't last for long... maybe about 15 seconds or so as it's coasting. When I accelerate the noise goes away. Any ideas on what this could be??

 

Wheel bearing?

 

I had a rear wheel bearing go out and was very tuff to pinpoint where it was coming from. Sounded like it was in the front end but was not.
