Spiderman,
Though the front bearing is no doubt a very precisely made assembly, I say it is built in such a manner that if there is sufficient grease present, the bearing could be either slightly loose or tight and still perform without failure for tens of thousands of miles. Is there something I am missing? There are torque settings for spark plugs, which I suspect 99 of 100 mechanics ignore, resulting only in some cussing at a later date when trying to remove them. I will now defer to your greater knowledge. DB
