I have a center differential pump from an 05' evo 8 . As far as I know it is defective. I'm not sure if it can be rebuilt or not. The cost of this bad boy new is $2148.33. So if you are intersted in it shoot me an offer. I'm not here to make a boat load of cash. I just want to get rid of the dang thing. It's just taking up space on my work bench. Here is a picture of it. Let me know if interested. Thanks!
