With the rear wheels off the ground and on jack stands, and in park the rear whe

ok wheels turn in opposite direction,. no it will not roll while in park selection indicator is in correct location when driving. its on stands because i'm changing pads. it just struck me as odd that they would rotate. should the transfer case hold the rear from turning while in park. Thank You

Normal operation as when vehicle is in park with wheels on the ground...one wheel CAN'T rotate opposite of the other..so vehicle stays put... What you're seeing is spider gear rotation with driveshaft locked in park while both wheels are jacked up off the ground... When shifted out of park... Both wheels can be rotated in the same direction. .. It does seem kinda strange!
