For you, I'd confirm if the clunk is there with the engine off.

Will respond in there. I had what I would call more of a flutter and it is gone with a strut replacement (had 45k on them) and engine mount (136k) for what it is worth

So what is the consensus on rear diff fluid. Car is out of warranty so I will go with Redline...what weight?

I just get a new plug/s each time. FCP lifetime warranty comes in clutch for this.

Thanks for the heads up on the FCP warranty. Will keep that in mind for the future.

I do my differential fluid every 30k miles. Yes, I realize it is a complete overkill probably, but the fluid that comes out is always much darker and some particulates than the one going in. I use OEM BMW Hypoid Axle oil, it stinks and I am probably overpaying, but I save on the labor by doing it myself, so why the heck not? I changed it at 30K, 60k, and just did it at 90k. I reused the plug at 30k and 60k, but decided to replace it at 90k. It never leaked, so if you are in a bind, just re-use it. It will be fine for a couple of oil changes.

Thanks. I did buy the BMW fluid.

Thanks for such an awesome spreadsheet. I drove my Volvo wagon for 300,000+ and intend to do the same with my bimmer.
