Capacity on both front and rear is just over 2 qts. If you have a factory LSD then you need the mopar friction modifier in the rear. It's a 4 oz bottle you add in to the 75w140. Front is 75w90. Lose the factory clamps and go get some worm drives. They are much easier to work with and will be less expensive than the tool for the factory clamps. Any pair of adjustable pliers will work in taking off those clamps though, it can be a little bit of a pain but they do work.
