There's a rhythmic sound emanating from my rear end, and I'm not sure what exactly it is. It varies with speed and is consistently present, regardless of clutch in/out, acceleration/deceleration, etc.
My rear end is a Dana 44 with 35 inch MT/R tires (4" suspension lift), mounted to a 98 Jeep Wrangler 4.0L. From listening to this sound recording (below), what would you say is the problem? (If I'm not mistaken, this particular noise is something that someone with a trained ear will be able to identify very quickly.)
