Should Nissan Differential oil be Changed out from 80w90syn to 75w140syn?
Was this a recall? And if something happens will Nissan replace replacement parts without charge.

The text that is now stamped on diff. covers should partially answer your question.

Even though the "new" diff is beefier and runs cooler, it needs the thicker oil. This tells you you the "old" style diff. needs all the help it can get by being filled with thicker synthetic oil.

I read this from someone elses posting. I guess I should have looked into it before posting. Oops!!! I own a 2004 But Thanks for the info.

I thought the 2004's were recalled to have the "new" style heat sink cover installed, along with the 75W-140 lube????

To date, there's been no recall on the rear end, fluid, or otherwise.
There is a TSB that reads if a 2004 Titan is in for rear end service, the rear diff cover should be replaced with the larger finned cover and synthetic 75-140W fluid added.

Some people have been lucky in getting their dealers to switch out the cover and fluid for free-others, not so lucky.

That's what I was thinking of. Guess I should have worded my previous statement differently.

Yeah, I have the older style (metal) I would like to have the larger finned type.

You can buy the finned cover from courtseyparts.com, they are a site sponsor here. I think it is around $125.

For $125 you can by a Stillen finned diff cover.It holds almost 1 quart more fluid than stock.
