"O" come on Level2, you just wanted to take this opurtunity to brag about you having a torson (lucky dog) ha ha. I don't think the regular rear diff does have synthetic, at anyrate, mine does now (royal purple), and a detroit tru-trac, naa naaa naa naa !!

someone correct me if I am wrong but I think it depends on the year. the bigger trucks like F250 and up went to synthetic in 99, and I was thinking the F150s etc went to it in 01 or 02 including the ranger, I do know that my wifes expy 2003 has synthetic and I was thinking that my codrivers 04 ranger had it also (can't check as he traded it in a couple months ago)

The torson doesn't use a friction modifier as it is a gear driven unit, the clutch type lsd do need a modifier. I don't know monsterbaby, I take it your talking of the rear diff. I put synthetic in mine when I swapped in my lsd. I allways asumed the factory used dino fluids. I think I'm fixen to get an education by someone.

Wendall I am talking the rear diff, easy way to tell check the owners manual it will tell you what the factory put in. and the guy that made the comment about 10w-40 I bet that is actually 75w-140 gear oil.

OK, I got my manual, mine is an 04, and it says to use motorcraft SAE 80w-90 premium rear axle lubricant, all, except fx4 level 2, level 2 uses motorcraft SAE 75W-140 SYNTHETIC REAR AXLE LUBRICANT. So, as of 04, only the level 2 had synthetic.

cool to know, wonder why though. On a side note you can change any of them to synthetic but do a good job cleaning out the old first. I run synthetic in all my vehicles diffs except the race truck, and wouldn't hve it any other way.

because at the first sign of water degradation I change it. I always change it once a year, and check it after any race that had a lot of water on the track, and sometimes I change it because it just feels like it's possibly contaimined or I feel a need to check the gears for wear. Also the truck only runs about 4 seconds at a time under power so it doesn't really get hot, and since I run full spools in both ends I don't have to worry about spider gears or locker gears. so I can't see spending the money on synthetic for as often as I change it and the little use it actually sees, remember in a year that truck probably actually gets less than 10 miles put on it, 200ft at a time.
