Does the fulltime 4wd transfer case use a special oil? My rig didn't come with a book, and I misplaced my service manual. Also does the front differential use something other than 75w-90 gear oil?

 

Atf +4 for the t-case. I just used regular viscosity range gear oil in the axles.

 

I was hoping that was it, have some left over from tranny service

 

Remember to use LSD type gear oil of you have LSD. I used that in both ends of my R/T.

 

Crap I'm glad you said something..all this time I hadn't thought about it because I didnt think i had one, then you said something and I went and checked my buildsheet...

Now I have to remember what kind of oil I put in it. If I didn't have the additive, would I have a noticeable chatter or anything?

 

No adding special stuff needed these days. There are many brands of ready to go LSD quarts of gear oil.

 

True, but if he forgot to get the oil with the friction modifier already in it, he can just add it to the oil.

 

Wonder if I should put a bit in just to be on the safe side. Shouldn't hurt anything to have some extra right?

 

I didn't, and am not worried at all.

 

The problem is I have no idea what kind of fluid I put in. Chances are I was too cheap to get a decent oil.

On a side note, do all of the r/t models come with awd?
