Ok, this may be a really stupid question, but I'm changing the rear diff oil for the first time. Do you need a gasket for both the drain plug and the filler plug, or just the drain plug, or no gaskets at all? I have an '03 Sedan w/AT. Also, if I need to get a gasket, will most auto parts stores have the gasket in stock, or am I better off getting one at the dealer?

 

i didnt change mine... it is a aluminum type gasket. it doesnt crush like the oil pan plug.

 

I just found this posted elsewhere. It's from the Infiniti Service Manual. It says not to re-use the gaskets. I take it you haven't had any leaks? Does anyone know if you have to buy the gaskets at the dealer vs. Pep Boys, AutoZone, etc.?

 

I just ordered some of those from my dealer. Two for Diff fill/drain and two for 6mt fill/drain.
Buck 75 each.
Don't know about auto part stores, though probably cheaper, but buck 75 each from Dealer aint gonna break my bank.

My service manual states the same...don't reuse.

 

My dealer didn't even have them, and they said they only ordered 2 of them, ever.

 

I thought I was getting some bad info when my dealer quoted me $8.50 each. Anyone know if these would be available at a Nissan dealership?
