I have 2003 Level II, I do not have an owners manual. It's about time to change my drivetrain fluids. Any know of the fluids to run in the stock 8.8 diff (with torsen LSD). Also looking to change the front diff and transfer case (all are stock)

Thanks,

The Torsen diff requires synthetic 75w-140. The front uses a 90 weight oil such as 80w-90 or 75w-90 (it doesn't really matter which, conventional gear lubes are USUALLY only available in 80w-90, synthetics are usually 75w-90) front diff only requires conventional but you can use synthetic if you want. Transfer case uses Mercon transmission fluid.
 
Thanks. I found a lot of conflicting information on various auto part sites. A couple of reliable sources say the same thing.:icon_cheers:
