So you knew they were like this when it was new. Now that its going over two years they might not do anything for you? Like I said a little earlier its normal for ball bearing to have a very play in them but not no 1/2 inch. You should only feel a few thousands play which is normal for ball bearings but not tapered bearings. It all most sounds to me like someone put the wrong bearings in it somewhere along in its life??? I sure hope you the best of luck with the dealer but I have worked in dealer ships and I just have a feeling they are going to ask you why you waited so long, so sure don't tell them you knew they were like this from day one. You can measure the spindle size, wheel bore size and the width of the bearings and buy new bearings in most auto parts stores like NAPA. If someone can cross the bearing size to a bearing number for you, you can buy new bearing on E-Bay. For sure don't go by the old bearings if they are the wrong bearings but by size. Hope you the best of luck on this.
