Noise from 2000 Druango at freeway speeds..?

From : mr

Q: dennis wrote thanks guys for the information. i jacked both rear wheels off the ground and they turned in opposite directions. so it must be open differential. i think ive got a 2001 ram rwd that was ordered with limited-slip. when i turn a corner from a standing stop the rear tires frequently squeal a little and feel like they want to hop so im thinking that i really do have limited slip although when driving off road or on snow/slush during the winter i find i dont have the traction i think i should have when driving on say wet/soggy terrain. .
