Well with all the talk about the rear diffs on the new trucks being low I just had to take a look for myself and guess what- mine was 3 pints low <br>Now I suppose that DC put the fill whole in the wrong location making it now 3 pints over full or the factory machine is short changing the diffs. For now I will run it up to the fill hole. <br><br>So whats in your differential?<br>

 

Mobil 1 GL-5 synthetic 75W-90 front and rear to the bottom of the drain hole.

 

Synthetic GL-5 8)

 

Same as Nevada here.

 

Have you found that the fluid in the rearends have been lower than the fronts (on 4X4's) I didnt have too add any too the front

 

Rear end holds about twice as much GL-5 as front end.
