LMM: slight vibration

[thetwinsduramax]

Okay, it may all be in my head but.

I had a Rear Main leak, the stealership warrantied of course. The deal is, I feel a slight vibration while at 65mph+ like a rear tire balance issue. By that I mean I feel the vibration in the seat more than in the steering wheel. Could something have be done wrong to create this vibration.

BTW, twheels were checked, not out of balance.

Maybe the driveshaft is out of balance?

Yes it is 4wd.

I'd love to take credit for the avatar, but i image searched it. Wanted to have something different than my truck until it has some more done to it.

I think he was asking if you are sure your truck is not in 4wd right now.

...dope...No it is not 4wd. I have twin toddler sons. I check it pretty much everytime I get in the truck just to make sure.

Thanks for the catch.

could try flipping the drive shaft a few teeth in the tail shaft I think I read somewere there is a mark that some are set at.
