2024 Supra possible diff leak

[ky.supra]

I did two diff fluid changes, on my car and my friend's car. Pretty quick procedure, give or take 10 minute job. I pour back the old fluid into the quart bottle and seems to be a little over half a quart upon inspection. I hit 40k miles last week, 2 track days last year and this is my first diff fluid change.

Thanks for the photo, Kevin. So, the fluid capacity is a bit over 1 liter, meaning half of that is left behind?

No problem. Yes, the old fluid I drained was a bit over half a quart.

If you take the black weight off it's cake to get to. The weight takes like 50 seconds to get off, if that.

Go you know what bolt size that is for the dampener?

Since this is still fresh on my mind

- E12 torx to remove dampener, 21 ft lbs to tighten

"BMW is urgently working on a solution to the problem." - So they should have one ready in... two weeks?!?

Good point. I wondered the same.

Just keep driving and my guess is there are 68 to 70 more drops of diff lube to weep out before its happy.

It looks like you have experience.

I’ve not read pages 2-19, but is this a 20 page thread on a diff leak where no one has yet taken out the diff plug to see if it’s over/under filled? (Toyota/owner/anyone?)

Seems like something simple you would want to know before continuing to drive the car around, but sure I have missed something from pages 2-19.

Hush with your logic.

I spoke to a BMW shop tech with many years of experience with ZF transmissions. I described to him exactly what has and is happening regarding leakage of diff fluid.
He told me to keep an eye on the leakage rate. The amount that has leaked is probably 1/2-ounce.
Apparently, that is no cause for alarm. I will check the level, soon.

Question: I believe the rear central jacking point is the diff. Is that true? I plan to buy the tools I will need, drive the car up on home-made wooden ramps, then jack up each end before sliding a Rhino ramp under each tire.

Yes.
