Even if you exessively beat on it, carry a large load or run it low on oil... there's no good explanation for "blowing" 2 diff's in 3 years. Especially on a supercharged 2.8L. I mean, it's not like a 2004 E55 AMG diff!!! I'd say Mercedes has a defective part. What goes wrong? Are they just whining or are the ring and pinion gears breaking? Is this model limited slip?
