so I heard this "wuring" sound when the when makes a full revolution at walking pace, thought warranty is almost up best get it looked at. the guys at ford thought it might be a bearing that has collapsed. I get a phone call saying the axel is bent...... I ask how as the heaviest thing ive put in there is my cricket gear. I asked if it would of caused any damage to the diff, and to my delight they have ordered a whole new diff and rear end for my ute. so boys if you hear something strange, get it looked at!!!!!!
