just came across some wheel bearings packed with grease on a drive axle. Oil mixing with the grease. Any harm to doing this?
Any harm to grease packing oil cooled wheel bearings?

When a drive axle wheel end is serviced correctly there should be no need for grease. When I see this, I automatically think someone is trying to cover up something, like a wheel seal that was messed up or rusted seal surface.
Biggest hiccup is your relying on grease now to lube and cool the bearings, when its supposed to be oil. Oil cant flow through the bearings as designed.
Id make it right if it were in my bay. Any less is asking for trouble. IMO -

Grease in oil lubed bearings is a big no-no. Either they're trying to cover up a leaking seal or its a simple lack of knowledge.

Sometimes people are taught incorrectly and other times they just make dumb decisions because they dont know any better. You hit the nail on the head. LACK of knowledge.Bean Jr., Dino soar, blairandgretchen and 1 other person Thank this. -

Drive axle you just make sure diff is full, then jack one side up a couple inches, then the other. That lets the oil from the housing run down into the hub. Then just check/top off the diff.

There is a plug on most drive hubs that let's you fill the center cavity after a repair. Takes the guess work out of it
