So three weeks after doing this work my front bearings seem to dead, i.e. there is a 'roar' coming from the front end particularly at higher speeds. I did re-use the bearings so perhaps they were already on their way out, but I'm still concerned that I am doing something incorrect, e.g. I'm using the dial indicator incorrectly and set everything too tight.

Can anyone point me to good description for how to use the dial indicator to set the correct tension on the bearings?

Also, is there any reason the outer wheel bearings cannot be replaced while the calipers are still on?
