Did my 7.25 take a crap?

I get a pretty decent whirring/grinding noise

re read what he said THE DRIVESHAFT AND WHEELS ARE NOT TURNING! he has his foot on the brakes, so it cant be the rear causing the noise,

i agree with caferacerx at this point the only thin that can make that noise with the brake ON is inside the trans area.

IMO time for a rebuild.
