I have a 2002 WRX donor. I have been working on getting everything ready as I can. Here is the problem I ran into. The trans. uses a female SFJ freering tripod joint held on by a circlip on the front axle shaft. The rear outer CV that goes into the rear hub/rotor assembly uses a SFJ double offset joint that is a internal snap ring that hold it on just like the front outer CV. We have to use the front outer CV housing to hold the front wheel assembly together. You can see it in the gocart video. The problem is the front and rear axle shafts have different splines and you can't mix the CV's. This leaves me with a major problem. Since their gocart used a newer donor this may not have happened to them. Can anyone help with this. I spent a lot of money getting my trans rebiult and new rear wheel bearings. Help please. Thanks.
