OK so... 1999 chevy blazer, front passenger side sounds like it roaring from the car trying to go into 4wd, shad replaced the wheel bearing thinking it was a ABS issue, didn't fix it. We have also taken the 4wd fuse out and it still making the roaring sound.. sounds like I'm driving it in 4wd, I can come to a very hard stop and I hear a pop like under the front console and it stops for a bit then starts again. Any ideas?
