Experiencing the first rains since I purchased the truck, my (2010 "SSV" with 4WD) is having a hard time getting up my slippery dirt road in the rain. I recently almost got stuck in 4 Low.
I am running the stock tire size 265/70R17 Goodyear Wrangler All terrain Adventure (cop tires.)
My understanding is I should turn off the traction control when stuck, since it is applying the brakes, which makes it more difficult to get unstuck. I also believe both differentials (front and rear) are "open" and rely on the traction control / stability control system to prevent wheelspin in less drastic situations.
My primary questions are
1. Are both differentials in fact "open"?
2. If yes, is there a junkyard swap part (from pickup or other trim level Expedition) that has a limited slip differential?
3. I am looking at purchasing a TrueTrac limited slip unit (Torsen-like )for my truck's rear differential. Anybody have experience with this part?
FWIW, my diffs are 3.73:1 ratio.
Finally, my other truck has no prob getting up the road, but it has 37x12.5 inch tires with 4wd and Torsen differentials front and rear.
