Wanted to thank everbody who gave me info regarding the 06 IPB problem. Took what I had to the dealer. They had my bike on the lift and the primary apart before I left to get breakfast. Bearing and race replaced out of warranty no charge. Chalk one up for the dealer and MoCo.

 

Good deal, glad they took care of you!

 

I hope that does it for you 06WG. I had mine go at 3900-mi. Went again a few weeks ago (12.5K); waiting on IP-Case and Trans-Case. First time, they just replaced the bearing/race. This time, they're swapping in the '07+ cases that have the alignment dowels between them. If yours should fail again, have your service writer push for this fix. MoCo is doing mine on their dime, even though I have the extended warranty. I'm also going with the chrome IP-Case (cheaper than the black one!). I'm having them do a close inspection of the Rotor Screws while they're in there; the other '06 issue. Good luck to you.

 

Is the whirring noise gone? Mine was still there after the IPB and race replacement. So they opened her up again and replaced the tranny bearings.

The noise is still there.

 

Good deal, glad they got you in and out quick on there dime as well. I covered it myself since they wouldn't give me the parts. But they would have covered it if brought into a dealer.

-Side note-
I guess I will be the lone person thinking it isn't a alignment issue but rather a bearing/race assembled fit and luberication issue. The race fit's in that bearing pretty losely (for a bearing), and I question the amount of oil getting to the bearing. Personaly if mine goes out again I am looking for a sealed Bearing/race combo like the wheel bearings. But mine is quiet again and running strong as ever now. I got 24k miles out of the first one hope to do the same or better with this one.
Oh and my shaft run out was in spec as well.

 

Mine is also in the shop for the second time for the same issue. This time they are going to put the new cases on as well. I lost the first bearing at about 15,000 mi., and now that I have around 23k, the problem is rearing its head again.

My shop knows of the problem, but never heard of, or did the case replacements on any other 06 bikes. After speaking with the service manager on the case swap, he called HD, and was given the ok for the repairs. It will end up costing me 50 bucks through my extended warranty.
