I am one of the lucky ones with lighter (smaller diameter axle and seal) 3500k rated axles with zero (ok may be one if you split hairs) reports of leaks.
The VAST majority or leakers are on their 5th wheel units with no known root cause of failure or proof of a fix despite anything you read as of this date.
