Out of curiosity when you all are servicing the front axle hubs are you always replacing the snap rings or do you always reuse them unless there's some sort of damage done to them? Every time that I've ever serviced the front axle hubs (and they are due now again) I've replaced these things just basically because the FSM calls them "non-reusable" but I wonder whether that is truly necessary. Thoughts? Thanks.
