where can you find out what axles you habe has far as Dana 60,70, or 80 i need to know what fluid to use the book says... 9-14" rear axel uses 75W-90 and the dana's use 80W90. which one aplies to me?

 

You have a Dana 44 up front. And you have a Chysler 9.25 in the rear.

 

ok thanks

 

so i guess i need 75W90 in the rear and 80W90 in the front? the book is not real clear on that

 

honestly it doesn't make any difference. i used the valvoline 80w90 or 85w90, don't remember which, in both my front and rear. its all GL5 rated.

 

ok i will just go with 80W90. how much do i need for both front and rear do you know?

 

from the service manual. 10 pts = 5 qts for both.
