I only asked because if the driver's side, it may be related to the bushing replacement.
It is really up to you if you want to replace all the one-time-use bolts and axle nut. I would imagine the process would be similar to how we would do a rear spring change except you dont touch the spring:. remove shock, disconnect sway bar link, disconnect upper control arm from knuckle... should allow you to tilt down the knuckle for axle removal. However, the service manual calls for removing the entire knuckle. And I hope it just needs a new seal and not a sign the diff carrier bearing is failing.
