Is there a difference between the bearing inner & outer as I have just bought 2 sets from Burtons one set are both SKF but the part numbers are different the second set one is a SKF the other is a Timken they come in a premier bearing box so they all have different numbers but they all seem to be the same. I do know Fords don't do them any more is this a problem these are going in my track day car running slicks ?????

thanks IAN
