Range Rover Sport front differential failures

When differentials fail in Range Rovers, they tend to fail in front.  Over the years we have changed 3-4 times as many front as rear differentials.  I'm not sure why that is, as the same part is used front and rear.  Some say it's because of the traction control.  Others suggest the front does more work because those are the steered wheels.

We recently had a 2006 Sport differential fail, at 75,000 miles.  The truck had Mobil 1 gear lub all its life, changed at 15 and 45k miles, yet the bearings came apart as you can see.

I wish I knew what we might do to avoid repeat failures, but I don't.  For now, we fit the factory replacements and hope for a preventative answer

Land Rover Issued a "Special Service Message"--SSM41904 for failing differentials in the front and rear. The message states that the "paint/sealer" on the inside of the differential is detaching and contaminating the oil which results in overheating leading to leaks and bearing failure. Rover is aware of this problem, however they will not cover the cost of repairing this flaw unless your vehicle is still under the original warranty.

i've had two of these replaced in 2015. front and back on my 2007. what are the odds the OEM replacement have the paint issue resolved?

thanks to an aftermarket warranty, I've hd both diffs, the air compressor and two forward struts replaced. I guess I should keep it after the warranty runs out.
