Thanks for all the advice and tips. I'm glad to hear I am not the only one to experience this. My owners manual says to use GL-5 SAE 70w-90 Synthetic without any limited slip additives. I will change the oil in both differentials as soon as I can get to it. What is funny is that the manual also says that besides checking the fluied levels in the differentials there is really no maintenance required. However, as I mentioned earlier, the head mechanic at the dealership told me to change the oil every 15k when I bought the truck. I think he was trying to tell me to ignore the owners manual on this one because of what he had experienced with similar trucks. Thanks again for all the input. This forum is the best!
