The thing is the bumps doesn't load in one direction like when you are going around a turn. The bumps oscillate the motor back and forth rapidly which just beats the hell out of the rubber in the OEM coupler. It seems to be the people that consistently drive on washboard roads that complain most often. Just run through that EPS thread. People with issues are in Russia, Philippines, Saudi Arabia, Africa, ect.

Frequency vs magnitude. You can poke an elastomer a bazillion times if it's within it's ability to absorb the energy. Hit it hard a few times with a hammer, though...
I get what you're saying. With enough motivation to build an accelerated lifecycle test rig, I'd wager a friendly lunch bet over it.
