Just a thought for you...while it's apart again, have them replace the stator assembly with the new upgraded one. That is a second weakpoint of the 06 Dynas...the mounting bolts slowly back out and one day you'll have a hell of a chewing/grinding noise...the head of the bolt will back out and protrude inside of your stator and start shredding up the wound copper wires. The upgraded part gets rid of that bolt flaw, and while it costs about 220 bucks...since the cover is off...might as well do it.
I was going to live with my IPB noise for the rest of the summer...but my stator bolt decided to back out and ruin a ride I had just left for..turning it into an emergency limp back home.[/QUOTE]
Instead of spending $220 on the rotor just have the bolts tack welded. It can be done for about $20 at just about any shop. It will accomplish the same results.

Unfortunately there are no bearings on earth that will fix this problem. Harley will replace the bearings for free as it is a known problem on '06 Dynas. If you ride alot, they'll be replacing it evry year or so. The problem will never go away because it's a design flaw. The only way to fix it so it don't happen again is to (Man, '06 owners are gonna hate this) replace the transmission case and inner primary with '07 parts. I found that out the hard way after the second primary bearing lasted about four months. If you got an '06 and ride a lot and this ain't happened yet, it's probably gonna. I also did the stator/rotor upgrade after mine detonated. They also had a steering head clunk that they'll fix for nothing.

The Baker bearing works because it is actually a different design. The factory bearing is pressed on the shaft and not a sealed bearing. The Baker bearing is sealed and held on the inner primary case only. It is s slip fit on the shaft. The Baker bearing design has been around for a while, it was designed for high hp applications wher the factory bearing would walk and eventually fail. This is not an issue with the Baker bearing.
Baker probably make good stuff, but the problem is not caused by a bad bearing. When the bike was re-designed for '06, they didn't use alignment dowels to mate the trans to the inner primary. Over time these components will shift more and more till the bearing is the least of your problems. I had the original replaced while the bike was still under warranty. The replacement bearing lasted about four months and the noise started again, only this time I also noticed shifting was getting a little sticky. I had an '07 trans case sent from Milwaukee with my VIN# engraved in it, an 07 inner primary & a mile long list of small parts. Now it don't make noise and never will.

The Baker (or NTN) is the only way to fly. Ive installed a bucket load of them with NO failures. Currently have over 70k on one of the first installs. It wouldnt surprise me if it outlasts the bike. Dont take what you learn or read on the internet to be gospel.

My bike has actually had the updated case and alignment pins installed after the previous owner experienced IPB failures, and now it is going out again.
On a different note: Is there a "write-up" on here that gives a good set of instructions on how to install the Baker bearing? I have searched several times, but there is so much information about this issue I can't seem to find it if it exists.
