The Dmax CVs seem to be at a disadvantage from the factory though, with the differential sitting slightly further back than it other vehicles, and this puts more stress on them to start off with. Also, because of the extra lift in the front end, I've split the driver's side CV boot. (EDIT all good so far!). Any car maker that knows of a production problem yet lets cars get built & sold with so many defective diffs, front ends and gearboxes anyway is a joke.
