I am going to be changing the fluid in both my rear diff. and front diff., and I was wondering if anyone knew about how much it will take, I know there is no real measurment just an inch from the filler plug but since i don't wanna buy a case I don't wanna not have enough, I am going with AMSOIL 75W-90 for the rear and 80W-90 for the front....thenks for the help.

 

I think a total for both is 5 quarts 3 for the rear and 2 for the front If I rember right. I will find out soon its been a while since I have done mine. Thanks for reminding me!

 

Ya it is like 2 in the front and a little over 2 in the rear but not 3.

 

thanks a lot saves me from buying a case, I just called the guy who i bought it from, he said he has never changed the fluid so I hope it not too bad and I am using amsoil cause that **** is awesome...thanks for the help.

 

I use amsoil series 2000 in my truck also. It works great and i saw a little bit of mpg increase.
