FWIW, [FONT=Calibri, Verdana, Helvetica, Arial]My thoughts regarding later model Terrano front prop failures......
The front prop setup on the Terrano is probably very similar, if not identical to a live front axle arrangement,... as in the Patrol?
On the Terrano the gearbox is nailed to the chassis as is the front diff, so unlike a live front axle, there is very little movement other than that allowed by the resilient mounts.
With such a small potential for movement, the wear pattern on the “plastic” coating will be concentrated on a very limited area, unlike the live axle variant where the spline can be expected to move far more and subsequently distribute the wear over a greater area.
The earlier (grease-nippled) models featured steel on steel, with ability to lube, and would appear accommodate the concentrated wear far better than the plastic coated spline....
