I disagree to a large extent, but it can depend on load, operating conditions, oil type, and viscosity. You have two gears moving at 90° to each other under incredible shearing forces that will cause wear metals to be generated. Sadly, Dana 44 Advantek axles produce more for long periods of time versus other axle types. Ergo, you will always see paste on the magnets if the run is at least a few thousand miles.If you always get metal paste, I would say your not changing your fluid often enough. Many do no change gear dope the entire life of an axle, not saying any time interval would not work.
Admittedly if I was paying to have maintenance work done I would not change so often, or if I did not have a convenient place to do the work. I get enjoyment from maintenance activities, almost as much as actual machine use. The way I look at it I invest all my cost 'savings' into better materials. I keep my machines long term, if one has no plans to keep a car just do the bare minium recommended (this is why I never buy used).
In my 2019 Wrangler that has the same axle as the Bronco, I regeared from 4.10 to 4.88 to 5.13. On both sets, I had them REM Isotropic polished which produces a near chrome like surface finish and completely eliminates the need for heat cycles during break-in. It also substantially reduces the wear metals generated—but there was still wear metal collected on the magnets. It is just something that cannot be avoided, but can be reduced by the polishing.
