94 B4000 front end noise
I have a 94 B4000 4.0 5 speed 4x4 that makes a grinding/whirring noise when it is in 2 wheel drive. Im not sure if the noise is coming from the center of the truck, or the front end (cant tell which side). When I engage the truck in 4X4 the noise goes away. I have no idea what the problem is. It has automatic locking hubs. This may not be related, but the ABS light is also on and sometimes when I step on the brakes, I feel a crunching in the brake pedal, as I'm coming to a stop. Does anyone have any idea what the noise could be?? It sounds very bad and its loud. Ive taken off both front wheels and didn't find anything wrong...the wheel bearings feel tight. Any help would be appreciated!
