i'm ordering some amsoil gear lube and tranny fluid for my truck, i have awd so should the front be 75-110 like the rear? and withe the trx4 package i'm almost sure it has limited slip does the amsoil cover that or do i need additive for that? thanks josh.
sorry about all the questions just getting to know my truck, haynes doesn't tell you everything.

 

I am not sure about the AWD and I havent found anything in the manual, but the gear oil is 75w-90 (front) and 75w-140 (rear) for the 4wd...

 

i've been looking for a while without luck, just want to do it right. 75-140 is what i found as well not 110.

 

I cant really see what the difference would be between the AWD and 4WD axle oil wise.

Maybe one of the other guys will chime in!

 

If you have a LSD, you will need the additive. As long as you are using Synthetic, I would think 75-110 or 75-140 would be fine. But I have no experiance with AWD. I think Eric had AWD?? What say you o' exhaulted one?

 

i'll get the additive. hope my mpg's get better after all this. 11.78 sucks donkey nuts. just placed an order for pads/shoes,exhaust pipes,trans filters and belt. now i'm off to spend more on a cherry bomb pro. tax returns are great.

 

Mopar, I dropped down to the 11's also with this winter fuel. It was nearly 15 before under the same city only circumstances. Hope this makes you feel a little better that with the warm weather it will go up.

 

As long as the second number matches (the 140) you will maintain proper viscosity at operating temp. I couldn't find reasonably priced oil in 75W140 (it was all synthetic), so I went with 80W140. A bit thicker when cold, but the same viscosity at temp.

LSD additives I can't speak on...but gears are gears are gears. Particularly in our ancient axles. Regular, cheap gear oil of the proper weight will be just fine for the gears and bearings.

 

the front end is the same between 4x4 and awd, different parts in the t-case only
and wow 11 sucks, im getting between 12 to 17 mpg's depending on how i drive and im on 33x12.50's with awd

 

hey it's almost 12. ha. anyway i spend alot of time sitting in a stand still in the morning so i can understand. i bought a truck knowing mpg were not great. good fluid helps and so does driving habits, and sometimes i get road rage and the pedal goes down. so 90frnt/140rear it is thanks fellas.
