I used to have a couple of old land rovers & the rear axles broke once in a while but it
wasnt a big thing cause you could slip them out through the wheel hub & use 2WD  to limp
home (wouldnt work in a syncro) . At first I thought it was another legendary english design
problem but upon reflection I realized  it was an inexpensive weak link in my drive train &
fixable in the field (I tried welding a few ... didnt last ).  Bottom line it saved my
tranny when working in low gear ratios . You may ask yourself what  you prefer to save .. A
syncro axle or a tranny .

On the positive side . .. The land rover axles are encased & protected . The syncro axles
are not and I can easily see a shaf getting bent in the field by dropping onto a rock so a
heavy duty shaft could be of benefit .

another $0.02 for the pot
