I did, however, definitely learn 3 things from Brett: 1. what we call diffs are really final drives 2. change gear oil in final drives every 15k for durability 3. I will never buy a used E90 with more than 50k miles, unless I subtract $2000 from the sale price. Apparently BMW has truly made final drives 100k mile disposable by using two roller ball bearings instead of tapered.

Who's lifetime? Anyone that falls for that crap is an idiot, as you sort of suggest. 15K miles is the number I want to see on our diffs. Anything longer than that on a limited slip is simply adding unnecessary wear. Open diffs could go 30K miles without an issue, as there's nothing in them to contaminate the oil. Same with manual transmissions. LSDs create more heat than open diffs, which breaks down oil more quickly, but, also they create contaminates as the clutch pack wears. These contaminates will add to the wear, if they are suspended in the oil. Your test for an LSD is valid, but not relevant. The test will tell if the car is equipped with LSD or not (the M3 is), but it will not tell if the LSD is functional. Especially in the case of the E46 M3, E60 M5 and E63 M6, all of which have a combination Salisbury/Viscous unit with very low static lock. And the E36 MCoupe/MRoadster, which have very little static lock in their 4 disc Salisbury units. Also, the test you quote will not be accurate on Quaife/Torsen equipped cars. Hope this helps.
