Hello, I am one of the newest members here with a 2004 XC90 2.5T AWD Auto transmission

This car has the typical small fluid leak that seems to be coming from the bevel gear case. Any ideas where else this leak could be coming from? I'll try to take pictures.

WHat kind of fluid does the Bevel gear take?

The car has a small clicking noise in the front. When driving at a constant speed, if you let go of the gas pedal and stomp on it again, there is a small click, or if you stepo on the gas out of a red light, not necessarily too aggresively. It sounds almost like a universal joint. Anyone with something similar?

Thanks for any help

Kurt
