As far as I know, pretty much all LDUs put into cars anymore are remanufactured (I've heard rumors they quit making them, but can't confirm). All of the drive units since ~2015 use the same inferior single lip seal that is more likely to wear out prematurely. I've pulled apart a few LDUs that are less than 2 years old with serial numbers past 1M. Those ones have the newer style differential (6 spider gears instead of 4), but still use the same s**tty single lip seal. By the way, the revision letters end at Q, even though there are definitely some small changes in the motors made since 2017 (like the diffs), why they haven't kept track with further revision letters, I don't know...
If you've really only done 10k mi in 5 years, you should definitely check your speed sensor for signs of coolant... I've noticed that cars that don't get driven much tend to be more likely to have early failures than cars that get drive more often. Can't necessarily say that that is always 100% true, but it's a trend that I have noticed...
Thanks for the info. Here is what's on my 2017 work order:
ASY,P-TRAIN,MECH,COMPLETE,RC (1002633-00-Q) Quantity 1
ASY,HV COVER,INVERTER (1003783-00-B) Quantity 1
BRKT, HV CBL TO DRV INV, 2MM THK, STL (1019545-00-A) Quantity 1
SCR,M6-1.0X12,PH,TORX,STL,SEMS,PATCH (1011427-00-B) Quantity 1
Is that any useful?
