UPDATE, Vibration caused by BMF Wheels

I have a really annoying shudder from 65mph+. It will shudder for 10 seconds then kind of let up for 10, then come back.... anyway, it pulsates like that.

I thought my tires were out of balance so I had them balanced... not that. I figured I may have had a seperation of my tread, and it was time for new tires anyway, so I got new tires.... still a vibration. I wondered if a rim was shot so I bought new rims.... Still a vibration.

I thought It might have been a transmission shudder, so I shifted down to 5th to see if the vibration would change. Nope.

Brakes seem smooth and I feel no pulsing or vibration when I use them.

Only two things I have left that I can think of is a unbalanced driveline or a goofy alignment problem. Any input or idea's would be helpful.

Just a shot in the dark, but I've read a little about the "death wobble." Sounds like it could be the problem. You'll have to search around a bit to find symptoms that others have had....I don't have any first hand experience with it.

My 2008 does the same thing at around 72+ MPH. It feels like its in the right rear. Went through the balance the wheels thing and nothing. Will be checking the balance of the drive shaft next.
Just for the record my truck is a 2008 4X4 super cab long box dually.

UPDATE!!

Turns out it was these stupid BMF wheels all along. The third time that I was getting them balanced, the tech had me come and look at my wheels as they spun on the machine. 2/4 of the wheels have a crooked center and wobble a good 1/4 to 1/2" as they spin on the machine. The other two were perfect. He put them on the machine twice to double check. He said he usually only see's this on crappy cheap wheels. For the price I paid for these BMF's, they shouldn't be a crappy wheel!!!!!

I ordered some XD's since I've had them on several of my rigs with no issues.

I'm Pissed!!!!
