my opinion is, years in use is the biggest killer.
metal fatigue of the housing flexing over and over.
the older it is, the less force it takes to meet the fail line. the axle housing flexes putting extreme pressure on the caps in turn binding carrier eventually the gears cant handle the extra pressure. then new stronger gears are put in,same thing happens to axles so their replaced so now the carrier cant handle the strain, then comes a spool.. then the caps fail. so a new pumpkin is used.. the housing ignored most all the time...
IMO i think flex actually helps the life span, when flexing stops it brakes. think of the slipping clutches in the pro classes.

ive been low 10s @3300lbs for 3seasons and never hurt anything.ive had good luck with 4.88s gear sets seems the thicker the ring gear they seem to last.ive ripped the teeth off of many 4.10s...too bad they dont offer a pro gear in a variety of ratios for the 8.75
make your own, heat in oven to 425 degrees for four hours the let cool slowly. Softens it up to give, not shatter, street gears are very hard and brittle so they last, not good for racing. This is old guy stuff, Noah used it on the ark.
