What is the best fluids to use in the differentials 4x4, and the transmission. I am going to change all fluids this weekend, and want to make sure I put the best in. Thanks

 

I was planning on doing this myself within the next couple weeks. I was gonna get Royal Purple fluids. I am interested in seeing what anyone else on here has to say about this topic also.

 

asfar as fluids to be honest ive never seen a big difference at all when it comes to brand. i think the main thing is really just makeing sure they are changed at the proper times and not neglected. as far as the rear diff make sure u use the friction modifier in there as well which u can get from crysler/dodge. it really is great stuff. keeps it quiet back there. oil every 5000 miles. diff.. can't remember off the top of my head. as well as tranny.. ill have to check that.
