The inner on my driver side got to the point where I couldn't ignore it anymore. So I did axle upgrades and the inner seals last summer. I used the seal install tool, made it a bit easier. I replaced all the shafts, bearings and hubs ect... while I was at it. I just did a quick sanity check with the dial indicator before I closed it up. I checked it before I dropped it out and no change.
