Diff oil level measuring tool?

[shiv.nandak]

Is this the washer you are looking for ?

Are you supposed to replace that gasket? I was told to reuse it and have not had any issues in 6k miles.

I'm pretty sure an O-ring like that will last until the next oil change at 50,000 miles, and probably even another oil change at another 50,000 miles. On the other hand, an O-ring like that only costs a few cents, which is why many dealers always replace them to avoid warranty claims on their work. As long as there isn't a large puddle of oil under the differential, I wouldn't worry.

I have 2. One for each diff, so I can’t spare one.

If we get the manuals, we will know exactly why we can no longer use these tools.
