Re: Clio rear bearing failure
The centre of the one-piece bearing is solid so over-tightening is unlikely to cause damage. In other words you are tightening against a solid piece of metal. In my experience most early bearing failures are due to poor fitting technique. Usually were pressure has been applied to the centre of the bearing and not solely to the outer race. Also some models have a spacer on the stub axle and if this goes missing then it is certain the bearing will fail.
If you look closely the guy in the video clip made an error. Watch were he rattles up the nut with the impact gun. He then attempts to torque the nut but the torque bar clicks without any sign of movement of the nut therefore the nut was already overtightened although there is the possibility it may be correct but he has no way of knowing and as the nuts are a use-once only fitting he can't undo it and try again.
