I have a 2006 wide glide. So far I've had to replace the stearing head bearing (under waranty), and now just had to replace the main shaft bearing, the main shaft seal and shift seal. The tech told me that they have to do this a lot on 06 & 07 dynas....

 

That really sux.

 

i wonder if they have a gounding problem. if the everything is not gounded as it should. the voltage will find its way to ground, often times through bearings. when this happens, obviously there is arcing and will ruin bearings fast.
just a thought

 

Reason being is what ? Would the 6 spd Gear Box have anything to do with it?

 

6500 my inner primary berring failed
There was a note in bike folder about having to do that repir at every 15000 mi

 

That sucks! What was happening that tipped you off to the problem, noise?

 

I developed a leak coming from somewhere under the primary.. this was the main support bearing and the main shaft seal. If you start hearing grinding noises from your primary, or certainly if you develop a leak, go to the dealer and get it fixed.
