Front and rear differential oil change

Ugxibowden · #1 03-15-2018, 12:39 PM

Hi all

Was wondering if any of you know what type of gear oil is needed to re fill the front and rear differential.
Also what type of fluid is needed for a transfer case drain and re fill?

It’s for a 2002 Ford Ranger Edge Plus

Thanks in advance for the information

I did all this on my '02 Edge 3.0. From the manual I have-
Front: 80W90
Rear: 80W90
supposed to add some friction modifier but I did not bother with that.
Transfer case: Mercon(R) XT-2-QDX

Theres a reason ford says to put friction modifier in the diff.. but i guess you know more than them.

They say it to make the diff run smoother. They can on occasion chatter without it. But with a 26 year old diff your not likely to have that issue.
