Can someone please tell me why my front differential keeps burning out. I had to replace my front differential twice within the last 6 months.it’s a 2004.

In what way has it burned out? Seals, Gears, Bearings? How did you become aware that something was wrong? Was it noisy, or leaking, or did it just throw something thru the case?
