I have a 2004 Ram 4x4 with 4:10's I changed the fluid now it seems to want to stay locked up... Is there anything special with these I need to know? Additive maybe?

Thanks
Tom

 

Ok, now I am thinking this could be the transfer case....it does it in the front when in 4x4.. What is the fluid recomendation for that? also how full?

 

I don't know if you have posi or not. If you do, there is a friction modifier you need to add when you change rear diff fluid. You can get it at Pep Boys, etc in a 4 oz tube. I don't have the manual in front of me, but the fluid recommendation is in there. Mine's the 3.93 and if I remember right it called for 75W140 synthetic.
