Can you explain the staking process? I read somewhere that once the old bearing is removed the next step is to check for staking burrs and if any are found they need to be lightly filed away to create a smooth surface before the new bearing and seal are installed. Then, after installation of the new bearing and seal use a large punch to stake it in. Why is this necessary? Seems to me when everything is back in place and finished it would automatically be permanently set in place. Thanks!
