Yes,I believe a much beter engineered DS should become available.
They sell the gearset which is the cause of the failure.This has been one of the most common upgrades from Ford for a very long time.
The cause of the failure is not upgrading the gears, it is driving the car with upgraded gears at twice the speed limit.
You can't just slap on an aftermarket performance part (in this case gears) and push the car's limits without accepting that you might require other prerequisite upgrades
And my stated "5% of owners" is probably a gross exaggeration
Better engineered driveshafts are
available. If you think Ford / Ford Racing should offer an aftermarket driveshaft, or even as a factory option, that makes perfect sense, but to put in a performance driveshaft as a stock part and bump the price of the V6 is a bad business move.
