Ok fellas, i have an 08' 4x4 with the 5.4. When i back out of a parking spot for example the rear end "Clunks" when i but it in drive and give it gas to move. Also does the same when your driving fwd, put it in reverse and try to back up. I had a 98' 4x4 ranger that had the same noise under same circumstances and it was recalled and repaired. Anybody got any ideas? Is this an issues that needs to be addressed? Thanks!
