Time To Change The Differential Fluid...Amsoil?

[Turbo Kidd]

It is time again for me to change the differential fluid in my 2003 4x4..... I want to run the Amsoil Severe gear fluid. However, I have a few questions first.



1. ) Should I be using the 75W-90 Severe gear?



2. ) Do I need to put the addiditve in the rear diff?



3. ) How many quarts do I need for the front and rear?



4. ) Do I need new gaskets, or are they re-usable? (Sorry, never did this before)



Any information would be most appreciated!



Thanks!

Turbo Kidd if you don't ever tow then go with 75W90, but if you do tow some then you might check out Amsoil's new "middle of the road" 75W110 https://www.turbodieselregister.com/forums/showthread.php?t=176437

The Amsoil already has LSD additive I believe . . . Wayne can you confirm?

The rear gasket is reusable, not sure about the front.

1. Vaughn answered that



2. no, AAM axels do not need addatives



3. about 2 gallons will do both with some left over



4. nope, both gaskets are reusable. just clean off mating surfaces well, observe bolt hole orentation when re-installing gasket, they only go on one way.

When I change mine, I just loosen the bolts and break the seal with a screwdriver. After it's done draining, I retorque and I've never had a leak. Saves alot of time and mess. Some people like to wipe everything down, but you can't wipe down your engine everytime you change your oil so . . .
