Whine from differential - most likely causes?

[Philippe]

So there's starting to be a whine coming from the differential, low speeds.

What are the most likely causes?

Thank you.

your ring and pinion gears might not be lined up correctly and are meshing

No, the gears had already been changed when I bought the car September 2002, about 20K miles ago.

I was considering changing them anyway as part of swapping in a T5. Sounds like a really good idea now.

The car was in storage during the winter. Wonder if it goofed up the fluid.

While on the subject, what's a good brand for gears? I was thinking FRPP. I don't race the car. Just the occasionnal excitement at the red light.

FRPP are the only gears I'd use.

As far as the whine, try the easiest thing first - change the fluuid.

When does the whine occur, under load, coasting, certain speeds, hot/cold. The more of the info, the better the answer.
