Raven front drive unit 1478000-00-E vs. 1478000-00-D

[12Pack]

Just had my 2020 MS Raven Performance front drive unit replaced at 10 k miles. It’s a 1478000-00-E vs the original 1478000-00-D. Anyone know the difference?

I’m sure Tesla knows, but they usually don’t document these things for the public. Could be literally anything, even something as minor as changing the supplier for some bearing used inside.

Assume that later revisions have internal improvements, fixing things that have proven to be failure prone, etc - but they are rarely documented in any public way.
