Sparten locker ?
I noticed that you said with the Detroit True Trac to go with a dino gear oil. I have had one in for a little over a year now (rear 9.25 3.55's)
The shop that did the install is the most reputable in Las vegas told me to use synthetic. So I have been without issue. Have changed it 2 times in 5k to get rid of little bit of metal. Is clean now.
Does the ram rearend need the synthetic or can I use a dino oil. My front diff calls for a 75w-90 dino oil. Why does my manual call for synthetic in the rear and nonsynthetic in the front?
Thanks,

I've got True Tracs front and rear in my 1500 4x4 truck and am very happy with them. The truck is a beast in the snow. I had to dig a little to find straight dino gear oil, but it wasn't too difficult. When you do find it, stock up a little bit (get enough for an additional complete gear oil change).
