Torsen Differential??
I will be buying a 2005 Ranger XLT FX4 Level II this week.
I do not have the owners manual yet.
My understanding is that it has a Torsen Differential.
I have done some searching as to IF it needs the friction modifier or not.
My understanding after watching a video by Torsen is that it DOES NOT use clutches in its differentials.
Anyone have experience with this? Thanks!

You can go here, enter the vehicle info, to download a no cost copy of the Owner Manual. https://www.fleet.ford.com/partsands...owner-manuals/

Sorry, that might sound logical, but my Ford factory shop manual calls out to add the friction modifier (XL-3) to SYNTHETIC 75W-140 gear oil for the Torsen diff.!

We have to scroll down to the top of page 238 to find the sub note-1 definition. Looks like they have displaced it's location in the info stack, so is kinda confusing to find & interpret.
Anyway the FX4 Level-2 differential has a higher torque operating range, so gets a higher viscosity fluid specified. The XL-3 directions via sub note-1 definition (scroll down to read atop page 238) still calls out the addition of 4oz of the XL-3 friction modifier, to 5.25-5.5 pints of the synthetic 75W140 FX-4 Level-2 rear axle lube.

Ok, probably a good idea to change all the fluids if you don't know where it is on all past & present due scheduled maintenance.
Use the specified fluids that say in writing that they are licensed to meet or exceed Fords specifications & do that at least as soon as specified, or sooner if your drive cycle or operation conditions/environment meet Fords description for "Severe Service" & if so, follow the severe service call out for scheduled maintenance.
