So let me just say that at first I had a vacuum disconnect axle and had only heard this noise when in 4WD (aka front shaft was turning). I just recently swapped in a non-disconnect axle, and now even in 2wd (front shaft turns now) i get this weird grinding/howling noise. I'm going to assume it has to do with the front driveshaft? I've tried the powerbraking in 4LO as a chain test and it doesnt buck or anything. I know that my rear output seal is leaking too, but I doubt that would make a sound? Also, I know my front output yoke has some play in it. Any help would be appreciated. Thanks.
