Diffs, I'm fed up with the stock diffs they go crunchy so quickly no matter which balls I have in them. It might be the harshness of the shaft but I think it might be down to using a diff spring instead of convex thrust washers like Schumacher diffs for example. Only problem is the TC4 outdrives are too small for any of the washers I have, does anyone know of any that might fit?
