After reading several posts here I changed the fluids in my transfer case and front/rear differentials. I'd done the rear before but always with 90W as my manual (2004) suggests. I never got a notice about switching to 140W, so I used that this time on the rear, 90W on the front.
The transfer case was fairly easy, but I didn't have any new 'crush' washers as somone else on here suggested, so I used the old ones and also some high temp thread sealant. Anyone think that'll be a problem?
