It is not supposed to happen and the "wheels" are not supposed to be visible at the edge of the cups, I would say that there are only a few possible causes - -engine mountings broken / collapsed / misaligned (engine offset) -driveshafts incorrect for gearbox / inner joints -chassis very, very twisted (i.e. front wheels to far apart) you need to find a real decent dealer or independent, the dealer you've been to has treated the symptoms and hasn't cured the disease, your new driveshaft could go the same way if everything isn't in line. Have you looked at both tripod cups to see how offset everything is? If one side is all the way in and the other is just about to fall out then points to the gearbox being offset or twisted from where it should be. Sorry if this covers old ground but I'm new around here -- Liam Boyle
