This can also cause vibration and the bolt might end up removing itself after the bearing is completely destroyed. When that happens you are in a world of trouble. Don't ask me how I know...

Just something to think about...

We were aware of the possible problems and Andrew stayed in the car with his feet on the clutch and brake from the time just before the bolt was loosened until it was re-torqued. I feel confident that the trust bearings remained in place.
