I have no idea how old your truck is, however here's my take on it.
Is your axle original or rebuilt and does it have any grease nipples or nipple adapters? Assuming it is NOT oil filled and is grease packed as per your friend and if it was rebuilt or greased during service, I would suspect that a wrong type of grease may have been added.
Wrong type/cheap grease does experience premature thermal break down and turns into oil. Thatís my suspicion. If it is grease packed, pump sufficient Toyota recommended grease into your axle till all the old grease is flushed out. You'll know by the colour change when to stop. Be generous. Then check if problem still exists. I'd love to know what you find.
