Well CRAP!!! So… changed my diff oil yesterday, cleaned my locker magnets really nice, installed my GP101 diff magnets, replaced my front axle breather tube (had a big gaping tear in it, prompting all this), and installed my Carli diff guard. Decided to change my rear diff oil too while I was at it. Truck is a 2012 Power Wagon, manufacturer's specs call for 75w90 and say limited slip additive not needed. BIG ISSUE!!!!!!: Woke up this morning and realized I have a problem- I didn't notice it yesterday but, the 75w90 I bought has (noted in the tinyest letters on the whole bottle) "limited slip friction modifier included" so, how f-ed up is my truck now? I've only driven it about 40 feet- just moved it out of my wife's spot on the driveway and into mine. What should I do? Is just draining and replacing the fluid going to be enough or do I need to figure out a way to flush it out? (can't use brake clean to clean it out, it eats up the locker's wiring) Am I royally f-ed??? I can't believe I didn't notice it had the modifier but dang the print is small!!! (Yeah, I now realize it does say LS but, in ten times looking at the dang bottle I never noticed it, DOH!!!! I feel like a total idiot now that I see it!) Will it harm my lockers??? Thanks!!!
