So from what I can gather, Mobile 1 75W-90 Syn fluids for the diffs are acceptable as a replacement for OEM. But if you have e-locker rear diff, use the OEM one. Xfer case, use the OEM fluid...sound about right?
Need instructions for diff fluid and xfer gearbox oil replacement
Per the note in the sticky FAQ thread the link to the front and rear diff fluid replacement instructions are broken.
I have an '06 RR Sport HSE
I also need the transfer gearbox oil change instructions.
