Servicing C34 Stagea Diffs

[sleek3]

Hey fellow stagea owners,

As I have searched the diy section with no success, I just need to know how to service the diffs, isit like other diffs with a top and bottom bolt and also how much oil do I need..... Any help is much appreciated....

Also its a series 1 c34

Yes, just undo the filler first then undo the drain bolt. Takes around 1.5 litres? A 5L bottle will do both front and rear.

Im running 80w-140 in the rear and 80w-90 in the front.

Must be a magic bottle that has both 80W-140 and 80W-90 in it!!

I swing the bottle around, the heavier oil goes to the bottom.

If you've only got jack stands i'd consider paying a mechanic to do it

I bought the oil myself and the mechanic charged my $50 to change both diffs (+$25 for the transfer case, that was the cost of the fluid tho)

80w90 front and rear, atf in the middle (centre diff/transfer case)

How often does everyone change?

Pretty sure the diff is the same service schedule as the R34 - its in the major 100k service, of course you should always check it whenever you can...

On the stagea parts list it says to use 75w140 is 80w90 ok to use?

yeah, you can look up r33 gtr's on most oil websites they say 80w90
