Hi all,<p>I did as much searching as I could do on the topic before posting, but no luck in finding some answers.<p>I believe my bevel gear is has a slow leak in it. When doing the ATF on my XC90 last week, I noticed a thin coating of smelly oil on what I surmise to be the bevel gear unit aside the transmission pan. In order to assess any immediate risk, how do you check the current fluid level in the unit? I have an appointment at the dealer next week (won't be driving it until then), but would like to do my own poking around before taking it there.<p>Also, if the leak is small and/or slow, what are the general approaches to fixing it? <p>And one last question -- are the V8 models subject to the same bevel gear problem, or is the AWD system different?<p>Any help is appreciated. I'm a bit miffed that my CPO expired last month, and I specifically took the car in beforehand because of some strange front axle behavior that could not be reproduced. If this ends up being a problem they could have found then, I'll be raising quite the stink with Volvo NA.
