Differential and transfer case service needed?

Keep in mind the Front Diff (w/Torsen limited slip front axle) requires 4 oz of Additive Friction Modifier XL-3 or equivalent.

Did they bring this back again on gen3’s? I thought the raptors all had open front diff now & tremors got the torsen?

My 21 has the torsen LSD. I think most 21 & 22 models still came with but later 23 & 24's do not.

I am tackling this in a month or so at 30k; contemplating doing a transmission flush at same time while i do my own work. Truck has been trouble free other than one front strut replaced under warranty at 8k; i plan on keeping it a while.
