Hello,
I am ready to place an order for transfer and differential fluids but before I do can someone let me know if I made the right choice.
2006 Pathfinder LE 4L v6.
Thanks!
1. Transfer case fluid: Valvoline MaxLife fully syntetic Dexron / Mercon Automatic Transmission Fluid (getting 4 quarts)
2. Front final drive: Valvoline High Performance gear oil 80W-90 Limited Slip (getting 2 quarts)
3. Rear final drive: Valvoline High Performance gear oil 80W-90 Limited Slip. (getting 1 quart) I know I am supposed to use 75w-90 oil, but this one should do either. Right?
Transfer And Differential Fluids Please Check My Choice!

I use Valvoline Maxlife ATF in both the transmission and the transfer case. I use 75W90 full-synthetic gear oil in both the front and rear diffs, either Mobil One or Walmart's Syntech brand. There are also aluminum crush washers on the drain and fill plugs on the diffs and transfer case that Nissan recommends replacing; they are Nissan P/N: 11026-4N200. The copper crush washer used on the transmission drain plug (as well as the engine oil pan drain plug) is P/N: 11026-01M02.

Servicing the front diff is no different than servicing the rear. How often really depends on how you drive it, or more important, the conditions on which you drive your vehicle. Your owner's manual has your scheduled service intervals, but I doubt they have an interval for the diffs under the "normal" service schedule. I do mine about every 50000-60000 miles, using synthetic in both the front and rear, but my driving is mostly highway and paved side roads. If you go off road a lot, especially in muddy conditions, you'll want to service them more often.LessThanZero wrote:How often do you need to change the fluids in the front and read diff's? I know how to do the rear but what about the front?

Yeah, I have a 190,XXX on my 08 and I don't thing either the front or rear have been changed. That will be rectified tomorrow as I bought everything I need to change it today.smj999smj wrote:Servicing the front diff is no different than servicing the rear.

Make sure you check the vent lines at the same time.
I drive a fair amount of gravel, and when checking my rear diff for an apparent leak, I found that the diff was actually under pressure. This was because the vent line was completely plugged with dirt.
I ended up running a new rubber hose to replace the plugged metal vent line, as there was no way to unplug it.
Once I rectified the pressure issue, my leak stopped.
