Sorry to hear of your problems with the rear wheel bearings. I have not used the FAG bearings but others have with good results they say. I have used the SKF Explorer 6205-2RSH with no problems, lubricated, sealed, drift out and in. If they are fitted and installed correctly they shouldn't cause any problems. As I know the SKF Explorer bearings are good and there is some doubt about others, I will remove all references to any others from my next Alternative Part numbers update. I do hope your M3W settles down soon Wilson, it has been a saga.
