Circlip for Inner CV Joint - FTO 2.0 V6 & 1.8 DE3A If your inner CV joint can easily be pulled out of the gearbox by hand or you have gearbox oil on the floor this could be the culprit. If the joint is not held in tight then it's going to leak & potentially do damage over time. Mitsubishi Part Numbers MB160387 - 27mm (was MB526340) MB620144 - 29mm
