Bearing type noise from tcase. Normal driving the noise goes away with the slightest touch of the brakes. Wheel bearings are quiet. Noise is slightly louder when in 4hi 4lo and still goes away when applying brakes. Took driveshafts off to isolate the noise. Truck specs are 3.4 auto j shift case. Elocker rear, spartan front 4.30 gear. Anyone encounter this? Pictures and videos attached
