    Differential Fluid Replacement Tips

    The drain and fill plugs are M10 Hex. Torque them back to 55NM. The crush washers are 22mm inside diameter. One can be found locally at O'Reilly's, Autozone, or Advance Auto in the Dorman 66222 copper crush multipack:

    Also for the fluid the latest good fluid and what I used which has NO friction modifiers for quicker lockup is Mobil Delvac 1 75w-90 Gear Oil
    Found at Amazon. You will need a little less than 2 quarts so save the rest for your next diff oil change. Everything I found locally has some sort of friction modifier included.

      It's often impossible to unscrew the top drain plug without a special small socket.
      I believe it's this one: https://www.ecstuning.com/b-vim-tool...et/vim614~vim/

        I use a normal hex drive but you can’t get ratchet on but I just put a ring spanner on the hex
