official service interval that I've read was every 30K (rebuild limited slip at the time if equipped) which happens to be the same interval for trans filter and fluid.

Make sure the cover comes off instead of having someone suction the fluid. That way any metal shavings will be cleaned out before putting new gear oil in. Prepare yourself for some gross smelling stuff. Some people would change axle seals at the same time. I think it is extra work unless they are leaking.Originally posted by Toploader View Post

Gross smell is an understatement. I had to throw out a whole change of clothes as well as my trunk carpet that got that stuff on it. I think it's currently high on my list of worst smelling things ever.

HAHA, lol. It sure is, I almost had that crap dump on my clothes,
According to John 86vicky, I have an open rear (axle code 5), but I still used 75 W 90 synthetic oil (Mobil), since that was the only thing that was available"To Find yourself, you must first lose yourself"

I changed it at 90k or so in my 04. I thought I heard a little noise and figured it was time. The mechanic said there were some shavings, so I figure it was worth it. For what it's worth I can barely hear anything now so it was a win.2020 Volvo XC90 T6 Momentum (Ice White / Blonde)

You can tell gear oil is made from dead dinosaurs. I don't think they have quite finished decomposing either.86 Lincoln Town Car (Galactica).

Super slow. Burns oil too.Comment

When I had the diff rebuilt on my 90 Crown Vic a few years ago, the shop told me to drain the fluid every 18,000 miles. Since I put 25K miles on my car every year, that means I change the fluid once a year.Originally posted by sly View PostComment

You know my Avanti has 110K on her, only changed one time when I had to put in a new pinion seal in, actually two times the first time the "mechanic" did not put in the seal evenly, the second mechanic was like a watch maker, gently tapping many sides of the seal until installed evenly all around.Comment

Just a thought, before removing the cover be sure the fill plug will come out. Once in a while they get seized and you really don't want to find out you can't fill it after its already empty.86 Lincoln Town Car (Galactica).

I filled it up with 2 Quarts of 75 W90. It seems ok, but I would have to curl my pinky to reach the level, I guess I need to top it off with a third quart"To Find yourself, you must first lose yourself"
