about how much would it cost to change my diff fluid in my front rear and transfer case, i know i need like 90w and last time i tried to find it, it didnt exist, i also need to get some mopar friction modifier... i got this haynes manual and it tells me the amount i need in pints, so if anyone remembers the conversion from pints to quarts that would also be helpful

 

Why do you need friction modifier? Do you have a LSD?

Cost depends on how good a fluid you want.

 

yea i got limited slip

 

8 fl.oz. = 1 cup
2 cups = 1 pint
2 pints = 1 quart
4 quarts = 1 gallon

It might be a better deal to buy bulk and get a pump thing, plus the pump thing can make fills easier too.

 

You can buy a gallon of 85-90 gear oil at any auto parts store, the transfer case uses ATF.

 

Just did my front one yesterday it cost me $3.50 after the $10 coupon for pep boys. So if you don't have one of those about $15 an axle.

Also you don't need "90w" It is 80w-90.
