Axles Breaking 99 Boxster

[milliemax]

In my 500 years of experence, any time a spline fails you must replace both the male and female. Both have been stressed to the point of..... DISTRUCTION. So..one gives /fails and the other is ....STRESSED. Replace both...... and you can take this advice to the BANK !!! Max

Thanks for all the replies and to grubinksi for the measurement. FYI, I have been using OE replacement axles from junkyards, and the last axle came out of a car with 45,000 miles. Certainly, the car is launching on sticky Hoosier A6, which puts the car in the 1.8-1.9 60ft range. Going to try the Boxster S axles and swapping the transmission flange and hub to accommodate, rather than cutting the Tiptronic axles.

FYI, Pro Solo Autocross has drag race starts, and no wheel hop. Very uneventful, just breaks as the clutch is released.
